Etymology

The OED, in its revised entry, takes it as borrowed from New Latin embryologia, which is found in a work title of 1732 or earlier, formed from embryo and -logia, and compares French embryologie, recorded from 1762 or earlier.[2] Merriam-Webster Unabridged derives it from the French word.[3] Etymonline, the Shorter Oxford and Dictionary.com treat it as formed in English from embryo and -logy.[4][5][6] The first part goes back to Ancient Greek ἔμβρυον (émbruon, “young animal, fetus”),[4][7][1] from ἐν (en, “in”) and βρύω (brúō, “to swell, teem with”);[1] the second to Ancient Greek -λογία (-logía).[8]

Earliest recorded meaning

The branch of science that studies the formation and development of the embryo: about 1781, in W. Perfect's work on midwifery cases.[2] This is much earlier than the dates in other dictionaries: Etymonline has 1825,[4] and Merriam-Webster Unabridged about 1847.[3]

Semantic evolution

The word first named a field of study, covering the human, animal or plant embryo.[2] From 1840 it could also mean the subject matter of that field, the development of an embryo itself.[2] A person working in the field is an embryologist, from about 1850.[4]
