Surface Forms

Mesozoic positive

Morphology

Mesozoic = zoic (semi-transparent) = meso + zoic

The adjective is built from the combining form 'meso-' (middle) + 'zoic' (relating to life); these are technical combining forms whose meanings help in scientific contexts but are not common vocabulary for typical learners.

Etymology

Mesozoic comes from Greek parts meso- meaning 'middle' and -zoic from zoe meaning 'life' or 'animals', the same root as zoo. So used as an adjective, Mesozoic describes things 'from the middle life era', like rocks or fossils that come from the time when dinosaurs were common.
