deinflectfunction

The dictionary forms a written word could be conjugated from, with the path from each to the word: the endings are taken off one at a time, outermost first, as a learner does, so 食べなかった is the past of 食べない, which is the negative of 食べる. This only proposes, from endings alone, so it also proposes forms that are no word (食べなかう); the dictionary says which are real, by the kind of word each must be. findInflected and inflectedOf ask it. A form is proposed once, by the shortest path that reaches it. Nothing here fetches, and it never throws.

console.log(deinflect("食べなかった").filter((one) => one.base === "食べる")); // [{ base: "食べる", kind: "i", path: ["negative", "past"] }]

[ { base: '食べる', kind: 'i', path: [ 'negative', 'past' ] } ]
