jp-verb-conjugator

This module deconjugates conjugated Japanese verbs using a set of hundreds of rules.

Examples

const Conjugator = require('jp-verbs');

let result = Conjugator.unconjugate('言われてみれば');
console.log(JSON.stringify(result, null, 2));

Results in the following:

[
  {
    "base": "言う",
    "derivationSequence": {
      "derivations": [
        "言う",
        "言われる",
        "言われて",
        "言われてみる",
        "言われてみれば"
      ],
      "wordFormProgression": [
        "Passive Form",
        "て・で Form",
        "みる To Try To Do",
        "ば Conditional Form"
      ]
    },
  }
]

Grammar links (mostly from Tae Kim) are also included for almost all of the word types:

const Conjugator = require('jp-verbs');
const grammarLinks = Conjugator.GrammarLinkForWordType;
const wordType = Conjugator.WordType;

console.log(wordType.TE_FORM);
console.log(grammarLinks[wordType.TE_FORM]);

Results in the following:

て・で Form
