Rails Inflections:
What is it? Inflections in Rails, powered by the ActiveSupport::Inflector module, allow customization of how words are pluralized, singularized, or treated as uncountable.
Why use it? Sometimes Rails' default pluralization rules don't fit your app's needs (e.g., irregular words like footfeet, uncountable words like milk).

Examples

Default Behavior:


"person".pluralize  # => "people"
"person".singularize # => "person"


Irregular Inflections:


ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.irregular "foot", "feet"
end

// "foot".pluralize  # => "feet"


Uncountable Words:


ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.uncountable "milk"
end

// "milk".pluralize  # => "milk"


Acronym Inflections:


ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.acronym "HTML5"
end

// "html5".camelize  # => "HTML5"


Potential Issues:
Default Behavior May Be Inaccurate: Without customizing, words like "tooth" become "tooths" or "milk" becomes "milks."
Localization: Inflections are locale-specific, so customizations for one locale won't apply to others.
Best Practice: Always define rules for edge cases (irregular, uncountable, acronyms) in your config/initializers/inflections.rb ans restart the server after changes
