online thesaurus
B2Neutral to Formal
Definition
Meaning
A digital dictionary of synonyms and related words accessible via the internet.
A web-based application or site that helps users find words with similar or related meanings, often featuring additional functionalities like antonyms, example sentences, and word trends. The term can also refer metaphorically to any extensive, readily available source of alternatives or variations.
Linguistics
Semantic Notes
The term is a compound noun where 'online' specifies the medium. It distinguishes the tool from a traditional print thesaurus. While 'thesaurus' alone can imply either format in modern context, 'online thesaurus' explicitly denotes the digital, internet-connected version.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. Spelling of related words may differ (e.g., 'centred' vs. 'centered').
Connotations
Equally standard in both varieties. Slightly more likely to be hyphenated ('on-line thesaurus') in older British texts, but now almost universally 'online'.
Frequency
Equally frequent in both dialects.

- Avoid direct translation like 'онлайн-тезаурус' where context might expect just 'словарь синонимов' (dictionary of synonyms). The 'thesaurus' concept is less culturally entrenched in standalone print form.
Common Mistakes
- Using 'online thesaurus' as a verb (e.g., 'I will online thesaurus that word'). Incorrect: 'I looked on the online thesaurus' (redundant 'on'). Correct: 'I looked it up in an online thesaurus.'

FAQ
Frequently Asked Questions
Typically not. 'Online' is a standalone adjective. It may be hyphenated when used as a compound modifier before a noun (e.g., 'online-thesaurus search'), but this is less common.
A dictionary provides definitions, pronunciations, and etymologies. An online thesaurus focuses primarily on synonyms, antonyms, and semantically related words, often with less detail on definition.
Not blindly. Synonyms have different connotations and usage contexts. Always check the meaning of an unfamiliar synonym in a dictionary before using it.
Popular examples include Thesaurus.com, the thesaurus feature in Merriam-Webster Online, and the synonym finder integrated into word processors like Microsoft Word.
