embryonic

Etymology

The OED takes it as formed from English embryon + -ic, embryon being an older English form of embryo;^[2] other dictionaries form it from Late Latin embryō, stem embryōn-, and -ic.^{[3][4][5][6][7]} The Latin word is from Ancient Greek ἔμβρυον (émbruon, “a young one; fetus”),^[8][6][9] from ἐν (en, “in”) and βρύω (brúō, “to swell, be full”).^[8][6][9] Etymonline notes the earlier adjectives embryonal (1650s) and embryonate (1690s).^[8]

Earliest recorded meaning

Of or relating to an embryo: 1740, in a letter of the naturalist P. Collinson.^[2][5] Etymonline dates the word to 1819,^[8] and the Shorter Oxford and the Oxford Dictionary of English to the mid 19th century.^[3][4]

Semantic evolution

The figurative sense, at an early stage of development, rudimentary, appears in 1825 in Coleridge's Aids to Reflection,^[2] although Etymonline dates it to 1856.^[8] In pathology the word was used from 1884 like embryonal, apparently after French embryonnaire.^[2]
