Etymology

16th century, from Latin obvius (“being in the way so as to meet, meeting, easy to access, at hand, ready, obvious”), from ob- (“before”) + via (“way”). In order to avoid an awkward form such as *obvy, the Latin ending -us was maintained in the form -ous (which is otherwise equivalent to Latin -osus).

Pronunciation

• (General American) IPA^(key): /??b.vi.?s/, (fast speech) /??.vi.?s/
• (Received Pronunciation) IPA^(key): /??b.v??s/, /??.v??s/, (fast speech) /??v.j?s/
• Hyphenation: ob?vi?ous

Adjective

obvious (comparative more obvious, superlative most obvious)

   • Carried somehow, somewhither, for some reason, on these surging floods, were these travelers, of errand not wholly obvious to their fellows, yet of such sort as to call into query alike the nature of their errand and their own relations.
