circuitus

Latin

Alternative forms

• circumitus

Etymology 1

Perfect passive participle of circueō.

Pronunciation

• (Classical Latin) IPA^(key): [kɪrˈkuː.ɪ.tʊs], [kɪrˈku.ɪ.tʊs]
• (modern Italianate Ecclesiastical) IPA^(key): [t͡ʃirˈkuː.i.tus]
• Note: The second syllable may be long due to compensatory lengthening from losing the nasal of circum, yet it may also be shortened due to the Latin rule of having only the last vowel in a row be allowed to be long.
