Ortho

/ˈɔːrθoʊ/ prefix/adjective

Definition

A prefix meaning 'correct' or 'straight,' used in scientific terms, or short for orthodontics (teeth alignment), or right-wing (in some political contexts).

Etymology

From Greek 'orthos' meaning 'straight' or 'correct.' Used extensively in scientific nomenclature and modern compound words.

Kelly Says

Orthodontics literally means 'straight teeth'—the same 'ortho' prefix appears in 'orthodox' (correct belief), 'orthography' (correct writing), and 'orthopedics' (straight body)!
