Use this English morphology utility to generate a likely regular inflection for controlled text, examples, or preprocessing.

Word

Required string input.

Apply common English singular spelling rules and a small irregular-noun table to a lowercase plural noun. English exceptions are extensive, so treat the result as a rule-based suggestion rather than a dictionary lookup. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Singular form

The resulting singular form returned as a string.

• English inflection contains irregular, defective, invariant, borrowed, contextual, and style-dependent forms. Spelling rules alone cannot resolve part of speech, meaning, capitalization, compounds, or dialect.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Consult a lexicon for production text, preserve exceptions, and test ambiguous words in sentence context.

• English Pluralizer

  Apply common English plural spelling rules and a small irregular-noun table to a lowercase noun. English exceptions are extensive, so treat the result as a rule-based suggestion rather than a dictionary lookup.

• Comparative Adjective

  Apply common English comparative spelling rules to a lowercase adjective, choosing -er for simple one-syllable forms and “more” otherwise. Irregular forms such as good/better require a dictionary and are outside this heuristic.

• Regular Past Tense

  Apply common -ed spelling rules to a lowercase regular English verb, including consonant-y and short one-syllable CVC forms. Stress-dependent doubling and irregular verbs require a dictionary and are outside this heuristic.
