Definition: Someone with an egg-like head; a brainy/nerdy person.
Greek and Latin–
From Greek’s “oion” (“egg”) and “kephale” (“head”), and a Latin suffix.
Why this word?
I’ve always thought “egg-head” was a pretty unpleasant term; not necessarily regarding the type of person it’s used for, but mostly regarding how it sounds in my ear. (This might stem from the fact that I’m really not fond of eggs to begin with.)
Similar sounding words, like “hydrocephalus”, have always sounded better to me, too. I think it might be the “ceph” and polysyllabic nature of the terms.
