This webpage will automatically generate up to 10 random phrases from a grammar fragment. (Click here for a demo)
1. Input lexical items, one per line, first the part of speech followed by the word itself, separated by a space.
Example: N book
2. Input phrase structure rules, first the label for the whole phrase, then exactly one or two daughter nodes, separated by spaces.
Example: NP A N
(Hint: the maximum number of daughter nodes is two. If you need three parts, you need to combine two rules.)
(Advanced: affixes can be marked with a hyphen on either side, as in pre- or -fix. This will make the grammar more complicated to write.)
Typos are not tolerated (for example, extra spaces or blank lines). The generator can't guess what you want it to do!
