Synonyms

Look up English words and phrases in WordNet 3.1. Each group represents one meaning: read its English definition and examples before choosing an alternative. A word may have several unrelated meanings and parts of speech. Synonyms are other words in the same WordNet synset, not related words, opposites or an automatic rewrite. They are not interchangeable in every sentence.

Use an exact dictionary form. Case and outer spaces are ignored, underscores become spaces and repeated spaces collapse. Up to 128 printable ASCII characters are accepted, including punctuation used in names and phrases. Accents and other Unicode characters are rejected rather than silently removed. No stemming, spelling correction or guessed inflection is applied. For an unknown entry, suggested buttons show only dictionary entries beginning with the query, not synonyms.

The part-of-speech filter applies to the recorded meanings that have another synonym. Meanings without an alternative are omitted; if none have alternatives, the tool distinguishes this known entry from an unknown spelling. Source order is retained within each part of speech, with nouns, verbs, adjectives, then adverbs. More meanings adds eight groups. Copy supplies a unique list of the currently filtered alternatives without headings. TXT includes every filtered meaning, definition and alternatives, including meanings not yet displayed, and retains the full license notice.

WordNet is an English lexical database with historical, specialist and sometimes dated vocabulary. It does not cover every word or current usage. Definitions and candidates remain English when the interface language changes. Project and documentation · WordNet 3.1 license.

Only the dictionary section for the initial character is downloaded, normally gzip-compressed. Decoded bytes are verified; unsupported gzip decoding uses plain JSON. Failed loads can retry. Editing removes old results; obsolete responses cannot replace newer searches. Draft input stays in RAM across tool navigation; reloading restores car. Searches run locally in the browser without sending the query to a dictionary service.
