# Morphology.CustomPronoun

A custom pronoun behavior for use in a specific langauge.

## Declaration

```swift
struct CustomPronoun
```

## Overview

Overview Set a Morphology.CustomPronoun instance on a Morphology instance when you want to provide a langauge-specific customization of pronoun use in that language. Different languages have different requirements for the grammatical information needed to apply a custom pronoun, so you set custom pronoun behavior on a per-language basis. The example below shows how to create English “ze” and “hir” custom pronouns: let ze = Morphology.CustomPronoun() ze.subjectForm = "ze" ze.objectForm = "hir" ze.possessiveForm = "hir" ze.possessiveAdjectiveForm = "hir" ze.reflexiveForm = "hirself" Morphology.CustomPronoun only supports third-person pronouns. Use this feature when your app needs to refer to third parties with a specific pronoun.
