1    Aims

You can study English while having fun with English puzzle graphs. You will learn about word interactions while solving puzzles. The puzzles will help you understand how word connections can guide the building of sentences. Goals for working through the puzzles are:

    Each puzzle takes the form of a graph of words with labelled arrows that connect the graph nodes. The labelled arrows are clues for building sentence components. The puzzle task is to turn the graph of words with connecting clues into ‘solutions’ that are either a sentence fragment, a single sentence or multiple sentences of English. You can check your success by seeing if your solution matches the suggested answer.


2    How to read a puzzle graph

In a puzzle graph, word content for a puzzle solution occurs outside of square brackets (‘[’, ‘]’).

    The content inside square brackets tells us about word function, which is what words do in their sentences. These are clues that inform where words should go in puzzle solutions.

    Square bracket content should not be included in a puzzle solution. In contrast, all word content should be included. You never have to modify the forms of words, so a word should occur in a puzzle solution as you find it in the graph.

    Words and/or square bracket content can be the label content for a graph node. They can also provide the label content for a directed arrow that connects graph nodes. An arrow connects one node (the governor node) to another node (the dependent node). It is typical for the label content of an arrow to be square bracket content (what the dependent is doing for the governor).

    Most of the words needed for a puzzle solution are found in the graph, but sometimes you will need to add additional ‘invisible’ words. Some of the invisible words will turn out to be words that are involved with referencing what is talked about. These words can be:

Note that pronouns that cannot be associated with something else from the discourse context (called unbound pronouns) do have graph presence. Similarly, definites (e.g., the, these, this) that cannot be associated with something else from the discourse context have a graph presence as graph node content together with any following noun content.

    Other invisible words are words that have a formal role marking grammatical structure:

    It is also possible for node have as its content the underscore character (‘_’) and nothing else. This indicates an absence from a puzzle solution that we are able to associate to a meaning, as illustrated below in section 3.2.


3    Tips for reaching puzzle solutions

This section offers tips for reaching puzzle solutions. This starts with a simple puzzle. Then we gradually pick up skills to tackle more complex puzzles.

3.1    A simple puzzle

To form a puzzle solution, you can start by looking into a puzzle graph for an arrow that includes [arg0] in its label. The governor node for such an arrow will be the main verb content for a clause, possibly with other supporting words, while the dependent node will be the head word corresponding to the subject for the clause, which is the ‘do-er’ or ‘be-er’ or ‘have-er’ of the clause.

    Consider figure 1. This gives the puzzle graph for a single clause. By finding the arrow labelled [arg0], we identify were as the main verb. We also identify four_Rabbits as the ‘be-er’ (subject).

Figure 1: Puzzle graph for a single clause

    When the main verb of a clause is a form of the verb BE (like were) and there is no subject predicative connection ([prd2], as in Figure 2 below), then the [arg0] dependent will often need to occur after the BE verb that is itself preceeded by an instance of the existential marker there. With this knowledge, we can construct (1).

(1)
there were four Rabbits

Note that (1) includes there as the first word, and yet this word is not part of figure 1. This is an example of an ‘invisible’ word. As noted in section 2 above, the puzzle solution might need to include words that are not found in the puzzle graph.

    With (1), we already have a full sentence of English! However, (1) is not a complete puzzle solution for figure 1, since there are words that have yet to be used. One of these words comes at the end of an arrow that has four_Rabbits as its governor node. This word acts as an attributive modifier ([attrib]) to tell us about the size of the four rabbits (little). In English, numeral modifier four should occur before an attributive adjective modifier to give (2).

(2)
there were four little Rabbits

    Figure 1 also contains content for a temporal modifier with an arrow labelled [tmp] that has the main verb as its governor node and that points to the complex adverb Once_upon_a_time. After connecting these words, we get to the final puzzle solution for Figure 1 of (3).

(3)
Once upon a time there were four little Rabbits

    As another example, consider figure 2, which also has content for a single clause sentence.

Figure 2: Puzzle graph for another single clause

Searching for an [arg0] labelled arrow, we find that were is once again the main verb of the clause. The ‘be-er’ (subject) of the clause is names, which itself has an arrow labelled [genv] (genitive), which takes us to the genitive pronoun their. There is also an arrow labelled [prd2] (subject predicative), which provides content for ‘what their names were’ by taking us to and, which in turn takes us to four conjuncts. Each conjunct is linked with a [conjN] labelled arrow, where N is a conjunct's place in an ordering of all the conjuncts. Turning all of this into content for a sentence of English gets us to the puzzle solution (4).

(4)
their names were Flopsy, Mopsy, Cotton-tail, and Peter

    Now consider figure 3.

Figure 3: Puzzle graph combining figures 1 and 2

This third puzzle graph brings together content from the two previous puzzle graphs with connections of material at two different graph nodes. First, there is connection from the very top node of the graph with the word and. Nodes corresponding to the main verb nodes of the two earlier graphs form the dependent nodes of arrows labelled [conjN], much as we saw with the connections that led to Flopsy, Mopsy, Cotton-tail, and Peter. We can therefore expect to reach a puzzle solution that is essentially the content of (3) connected by and to the content of (4).

    But there is one further point of connection that we also need to make sense of: The arrow [genv] of figure 3 does not have a node with content their as its dependent like in figure 2, but rather takes as its dependent four_Rabbits, which corresponds to the four_Rabbits of figure 1. We can interpret this [genv] arrow connection as having an ‘invisible’ instance of their as the arrow's dependent. That is, the word their is absent from the puzzle graph because it's presence is captured as a direct arrow connection (referential link) to four_Rabbits, which occurs in the puzzle graph for independent reasons. We are therefore justified to take ‘(3) and (4)’ — namely (5) — to be the overall puzzle solution for the graph of figure 3.

(5)
Once upon a time there were four little Rabbits, and their names were Flopsy, Mopsy, Cotton-tail, and Peter.

3.2    An example with elision

Figure 4 has a similar structure to figure 3, in the sense that there are two verbs connected by [conj1] and [conj2] arrows from and occurring topmost in the graph. However, while the verb of the first conjunct is overtly realised with lost, the content for the verb of the second conjunct is shown as node labelled ‘_’ to indicate an absence (a lost lost!) from the puzzle solution.

Figure 4: Puzzle graph with elision

Following all the links of figure 4, we can arrive at puzzle solution (6).

(6)
He lost one of his shoes among the cabbages, and the other shoe amongst the potatoes.

3.3    A complex puzzle

This section demonstrates how to approach a complex puzzle. We will break this into stages, first building content for simpler graphs, which then combine to give larger graphs, and so ultimately lead to the final graph for reaching the overall puzzle solution.

    To start, consider figure 5.

Figure 5: Puzzle graph for a single clause

By finding [arg0], we can identify was as the main verb, and Mr._McGregor as the ‘be-er’ (subject). One other arrow extends from was. This is labelled with the preposition word on and the functional information [prd2] (subject predicative) and connects to and, which takes us to two conjuncts via the labelled connections [conj1] leading to hands and [conj2] leading to knees. One more connection, labelled [genv] (genitive/possessive), originates from and and leads to Mr._McGregor to capture the information that the hands and knees are those of Mr. McGregor. By following these connections and including his to capture the genitive/possessive connection, we can reach (7) as the puzzle solution.

(7)
Mr. McGregor was on his hands and knees

    Now consider figure 6.

Figure 6: Puzzle content for a participle clause

An arrow labelled [arg1] (object) extends to cabbages having started from planting with its [clr][dir] (closely related directional) modifier out. In turn, cabbages leads via an [attrib] (attribute) labelled arrow to young. By following these connections of the graph, we reach the sentence fragment (8).

(8)
planting out young cabbages

    Now consider figure 7.

Figure 7: Puzzle graph combining figures 5 and 6

Figure 7 has connections to bring together node content from figures 5 and 6. There is a [cnt] node (continuative subordinate conjunction) to state that planting acts as a restriction on the content from was. There is also an [arg0] connection from planting to Mr._McGregor, the ‘be-er’ (subject) of the main clause. A puzzle solution that meets these new criteria of Figure 7 is (9).

(9)
Mr. McGregor was on his hands and knees planting out young cabbages

    Now consider figure 8.

Figure 8: Puzzle graph for a single clause

Looking at jumped, this is linked to he with an [arg0] arrow, and to up with a [clr][dir] (closely related directional) arrow. Therefore, we can identify jumped as the main verb, he as the ‘do-er’ (subject), and up as an adverbial modifier, to derive the simple sentence of (10).

(10)
he jumped up

    Now consider figure 9.

Figure 9: Puzzle graph for another single clause

Looking at ran, this is linked to he with an [arg0] arrow. Also, ran is linked to Peter with an arrow that contains the preposition word after and the function information [clr][dir] (closely related direction). With these words and connections, we can derive the puzzle solution (11).

(11)
he ran after Peter

    Now consider figure 10.

Figure 10: Puzzle graph combining figures 8 and 9

This combines figures 8 and 9, with and to connect jumped and ran. Note how the single he connects as the ‘do-er’ (subject) to both verbs. A puzzle solution is (12).

(12)
he jumped up and ran after Peter

    Now consider figure 11.

Figure 11: Puzzle graph for a participle clause

We can see waving is connected to rake with an [arg1] ‘done to’ (object) arrow. A puzzle solution is (13).

(13)
waving a rake

    Now consider figure 12.

Figure 12: Puzzle graph for an imperative clause

The [imperative] node that has an arrow labelled [scope] to Stop tells us that the clause is an imperative with Stop as the verb of the clause. Typically, an imperative is an order or instruction for an unmentioned ‘do-er’ to do something, but also the ‘do-er’ can be addressed with a [voc] (vocative) connection. A vocative — figure 12 has thief — can occur either at the front or end of an imperative, making (14) a possible puzzle solution.

(14)
Stop thief!

    Now consider figure 13.

Figure 13: Puzzle graph for a clause with an embedding with the content of figure 12

This is the puzzle graph for a clause with an embedding with the content of figure 12. This embedding is connected by an [arg1] (object) arrow to the verb content calling with its [clr][dir] (closely related directional) modifier out. A puzzle solution is (15).

(15)
calling out, ‘Stop thief!’

    Now consider figure 14.

Figure 14: Puzzle graph combining figures 11 and 13

Figure 14 results from combining figure 11 and 13. Here, and has conjuncts waving and calling. A puzzle solution is (16).

(16)
waving a rake and calling out, ‘Stop thief!’

    Now consider figure 15.

Figure 15: Puzzle graph combining figures 10 and 14

Figure 15 has a [cnt] (continuative subordinate conjunction) node to combine figures 10 and 14, much like we saw happen with figure 7. Note how the verbs jumped, ran, waving, and calling all have [arg0] ‘do-er’ (subject) arrows that connect to the same he. A puzzle solution is (17).

(17)
he jumped up and ran after Peter, waving a rake and calling out, ‘Stop thief!’

    We are finally able to consider the overall puzzle graph of figure 16.

Figure 16: Puzzle graph combining figures 7 and 15

This has but to combine figures 7 and 15. Note how the verbs was, planting, jumped, ran, waving, and calling all have [arg0] ‘be-er/do-er’ (subject) arrows that connect to the same instance of Mr._McGregor. An overall puzzle solution for figure 16 is (18).

(18)
Mr. McGregor was on his hands and knees planting out young cabbages, but he jumped up and ran after Peter, waving a rake and calling out, ‘Stop thief!’
