Morphology

binomial = bi + nom + ial

Built from 'bi-' (two) + 'nom' (name/term) + '-ial' (relating to), so the noun sense 'an expression with two parts' is directly derivable from its components in typical technical usage.

Etymology

Binomial comes from bi- 'two' and nomen 'name'. A helpful image is a simple pair like x + y: a binomial is a 'two-term' expression or a fixed pair of words, so it means an expression made of exactly two parts.
