Tools (3)

check_moveread-onlyCheck whether the next word correctly follows the previous word in shiritori: it must start with the previous word's last kana, it loses if it ends in ん or was already used. Also tells whether each word is in the dictionary and what the next word must start with.
check_wordread-onlyLook up a word: is it in the dictionary, its reading, its first and last kana under shiritori rules (ー and small kana handled), whether it ends in ん, and which kana the next word must start with.
suggest_nextread-onlyPick random words that can follow the previous word (or start with a given kana), excluding words already used and, by default, words ending in ん. pool "everyday" (default) uses hand-picked everyday words, "common" adds common dictionary words, "all" uses the whole dictionary.

Schemas: list_tools.
