# `Plurality.Ash.Validations.SingularForm`
[🔗](https://github.com/jeffhuen/plurality/blob/main/lib/plurality/ash/validations/singular_form.ex#L2)

An `Ash.Resource.Validation` that ensures an attribute value is in singular form.

## Options

  * `:attribute` (atom, required) — the attribute to validate

## Usage

    validate {Plurality.Ash.Validations.SingularForm, attribute: :resource_name}

`nil` values pass validation (use `allow_nil? false` on the attribute
if presence is required). Uncountable words like `"software"` pass
since they are valid in singular context.
