Probably fromLatin-īvus. Mostly found in older, popular words; compare the neological borrowing-iv.

• IPA^(key): /iw/

-iu m orn (feminine singular-ie,plural-ii)

1. Forms adjectives denoting characteristics or qualities, especially relating to color; roughly equivalent to-ive or sometimes-ish.

The terms formed from the suffix often have the meaning of approximating or being similar to a certain quality (from the noun or adjective it modifies); it can be comparable to some uses of-ish in English: somewhat, approximately, slightly, rather: e.g.cenușiu(“grayish”),albăstriu(“bluish”). A suffix playing a similar role in Romanian is also-ui, especially with colors.
