# deinja

**deinja** is a lightweight JavaScript library that converts inflected Japanese words into their original forms.

Instead of aiming for perfect accuracy, *deinja* prioritizes speed and simplicity. It does **not** include internal dictionary data, which means it may return **multiple possible candidates** for each input rather than a single definitive answer.

This library was originally a component of [Mouse Dictionary](https://github.com/wtetsu/mouse-dictionary), and has since been extracted into a standalone module.

## Installation

```

npm i deinja

```

## Usage

```js

import deinja from "deinja";

deinja.convert("素早く"); // ["素早い"]

deinja.convert("転がし"); // ["転がす"]

deinja.convert("投げた"); // ["投げる", "投ぐ"]

deinja.convert("死にました"); // ["死ぬ"]

deinja.convert("終わって"); // ["終わう", "終わつ", "終わる"]

deinja.convert("しまった"); // ["しまう", "しまつ", "しまる"]

```
