Pronunciation

Forms

apos m or n (feminine singular apoasă, masculine plural apoși, feminine/neuter plural apoase)[1]

Etymology

It is inherited from Latin aquōsus (“watery, abounding in water”).[2][3][4][5][1] The Academy dictionary also compares French aqueux.[6] MDA2 allows a Romanian formation as well, from Romanian apă + -os, and Tiktin derives it from apă alone.[7][8] The Latin adjective is formed on aqua (“water”).[1]

DELR records the word in Aromanian and Megleno-Romanian too.[2] Its Romance cognates include Italian acquoso, Old French eveux and Occitan aigos.[3]

Earliest recorded meaning

The first record is in Dosoftei (1673), where the feminine is used as a noun for “the sea”: „Apoasa o trecu-n vad ca pe uscat” “he crossed the sea at a ford as on dry land”.[2][8][6]

Semantic evolution

The noun sense “sea” stayed with Dosoftei; the adjective means rich in water or containing too much of it, and like water.[2][4] Hasdeu noted that it was less used than its synonym apătos.[9] The Academy dictionary quotes it of unripe, watery fruit, of thin milk and of a river swollen by rain.[6] Anatomy uses umoare apoasă “aqueous humour”.[4]
