Synonym discussion
Sense: adjective/1
Broad is the most general of these, often describing something that covers many subjects or people ('a broad education'). Wide-ranging emphasizes variety across different areas, suggesting a collection of diverse elements ('a wide-ranging interview'). Comprehensive stresses completeness and thoroughness, especially for formal documents, reports, or studies ('a comprehensive analysis'). Vast is the strongest, conveying enormous scale — often physical — and can sound dramatic ('a vast desert'). Choose extensive when you want a neutral, precise term for large scope or quantity without the poetic weight of vast or the formality of comprehensive. For instance, 'extensive damage' sounds factual, while 'vast damage' sounds emotional.

Etymology
Extensive comes from Latin 'extensus', the past participle of 'extendere' (to stretch out), combined with the English suffix '-ive', which turns verbs into adjectives meaning 'having the quality of'. So the core image is of something that has been stretched out widely. The word entered English through French in the 1600s, first used in a physical sense (wide land) and later extended to abstract meanings (broad knowledge, large scope).
