Etymology Information

'holoblastic' originates from Ancient Greek, specifically the combining forms 'holo-' (from 'holos' meaning 'whole') and '-blastic' (from 'blastos' meaning 'germ; sprout').

Historical Evolution

'holoblastic' was formed in 19th‑century scientific English from the elements 'holo-' and '-blastic' (ultimately from Ancient Greek 'holos' and 'blastos') and became the modern English word 'holoblastic'.

Meaning Changes

Initially, it carried the literal sense 'relating to the whole germ/sprout,' but it became specialized in embryology to mean 'characterized by complete cleavage of the egg.'
