coadunate (ko-AJ-uh-nit, -nayt) adjective
United by growth; closely joined.
[From Late Latin coadunatus, past participle of coadunare, to combine,
a compound word from Latin co- (together) + ad- (toward) + unus (one).]
Coadunate ultimately derives from Indo-European *oi-no, meaning one, unique.
Less obvious words derived from this root include anon, atone, lonely,
eleven, ounce and inch. The lowly onion may also be in this family, conceived as a unity formed of many layers.
