How accurate is the noun finder?

The finder catches ~90% of common English nouns. Edge cases like nominalized verbs ('the running of the bulls') or gerunds may be missed.

Does it distinguish proper from common nouns?

Yes. Proper nouns (Sarah, London) are highlighted in a different color from common nouns (park, dog).

What's the difference between nouns and pronouns?

Nouns name things directly; pronouns (he, she, it, they) replace nouns. Use our Pronoun Finder for pronoun analysis.

Can a word be both a noun and a verb?

Yes. 'Run' is a verb ('I run daily') and a noun ('a long run'). The finder uses context (surrounding words) to guess.

How the Noun Finder Works

The finder uses a combination of rules: capitalized words that aren't sentence-initial are tagged as proper nouns; words after articles (a/an/the) or determiners (this/my/our) are tagged as nouns; and words with noun-forming suffixes (-tion, -ness, -ment, -ity) are also tagged. It uses a curated dictionary of 5,000+ common English nouns to catch the rest.

Rules & Tips

1Proper nouns are always capitalized

Sarah, London, NASA, Monday — names of specific people, places, organizations, and days. The finder flags every non-sentence-initial capitalized word as a likely proper noun.

2Common nouns follow articles or determiners

After 'a,' 'an,' 'the,' 'this,' 'that,' 'my,' 'your,' you usually find a noun. 'The park,' 'a decision,' 'my car.'

3Noun-forming suffixes

-tion (decision), -ness (kindness), -ment (movement), -ity (clarity), -ship (friendship), -er/or (teacher/actor). These suffixes are reliable noun signals.
