# Runs morphological analysis on input

`POST /morphology/{morphoFeature}`

## Request

- Base URL: `https://api.rosette.com/rest/v1`
- URL: `https://api.rosette.com/rest/v1/morphology/{morphoFeature}`
- Auth: API key in header `X-RosetteAPI-Key`

Returns morphological analysis of input. The response may include lemmas, part of speech tags, compound word components, and Han readings. Support for specific return types depends on language.

## Path parameters

- `morphoFeature` 'complete' | 'lemmas' | 'parts-of-speech' | 'compound-components' | 'han-readings', required

## Request body

- union
  - object
    - `content` string
    - `language` string: 3 letter code of language.
    - `options` object
      - `modelType` 'default' | 'perceptron' | 'DNN': Model type to use for Chinese, Japanese, Korean, or Thai. For Korean input without spaces, use `DNN`. For Chinese, Japanese, and Thai, use `perceptron` for an alternative algorithm
      - `disambiguatorType` 'perceptron' | 'DNN' | 'dictionary': For Hebrew only, determines disambiguator used. Default is `perceptron`. `DNN` is a deep nueral network model.
