- n. An organism at any time before full development, birth, or hatching.
- n. The fertilized egg of a vertebrate animal following cleavage.
- n. In humans, the prefetal product of conception from implantation through the eighth week of development.

Century Dictionary and Cyclopedia
- n. The fecundated germ of an animal in its earlier stages of development, and before it has assumed the distinctive form and structure of the parent; a germ; a rudiment; in a more extended sense, a rudimentary animal during its whole antenatal existance. In the later stages of development, especially in man and the mammals generally, the name fetus commonly takes the place of embryology In the cases of oviparous animals, the term embryo properly covers the whole course of development of the fecundated germ in the egg (which see, and see cut under
dorsal): as, the hen's egg contained an embryo ready to hatch. By a late and loose, though now common, extension of the term, it is applied to various larval stages of some in vertebrates, which in the course of their transformation are frequently so different from the parent as to be described as distinct species or genera: as, the embryo (first larval stage) of a cestoid worm.
- n. In botany, the rudimentary plant contained in the seed, the result of the action of pollen upon the ovule. It may be so rudimentary as to have apparently no distinction of parts; but even in its simplest form it consists virtually of a single internode of an axis, which upon germination develops at one extremity a leaf or leaves with a terminal bud, and a root at the other. In more developed embryos this initial internode or caulicle (often incorrectly called
radicle) bears at one end one, two, or more rudimentary leaves called cotyledons, and often an initial bud or plumnle. Also called germ. By recent authors the term is also applied to the developed oöspore in vascular cryptogams. See cuts under albumenand cotyledon.
- n. The beginning or first state of anything, while yet in a rude and undeveloped condition; the condition of anything which has been conceived but is not yet developed or executed; rudimentary state: chiefly in the phrase in embryo.
- n. Synonyms Fetus, Germ, Rudiment. The first of these words is mainly applied to the embryos of viviparous vertebrates in the later stages of their development, when they are more subject to observation. Germ means especially the seed or fecundated ovum, and scarcely extends beyond the early stages of an embryo. Rudiment is simply the specific application of a more general term to a germ or to the early, crude, or ‘rude’ stages of an embryo.
- Being in the first or rudimentary stage of growth or development; incipient; embryonic: as, an embryo flower.
- n. In the reproductive cycle, the stage after the fertilization of the egg that precedes the development into a fetus.
- n. An organism in the earlier stages of development before it emerges from the egg, or before metamorphosis.
- n. In viviparous animals, the young animal's earliest stages in the mother's body
- n. In humans, usually the cell growth up to the end of the seventh week in the mother's body
- n. botany A rudimentary plant contained in the seed.
- n. The beginning; the first stage of anything.
GNU Webster's 1913
- n. The young of an animal in the womb, or more specifically, before its parts are developed and it becomes a fetus (see fetus).
- n. The germ of the plant, which is inclosed in the seed and which is developed by germination.
- adj. Pertaining to an embryo; rudimentary; undeveloped.
- n. an animal organism in the early stages of growth and differentiation that in higher forms merge into fetal stages but in lower forms terminate in commencement of larval life
- n. (botany) a minute rudimentary plant contained within a seed or an archegonium
- A Medieval Latin corruption of Ancient Greek ἔμβρυον (embruon, "fetus"), from ἐν (en-, "in-") + βρύω (bruō, "I grow, swell"). (Wiktionary)
- Medieval Latin embryō, from Greek embruon : en-, in; see en-2 + bruein, to be full to bursting. (American Heritage® Dictionary of the English Language, Fourth Edition)
“(4) _Fundamentally the embryo of a higher animal form never resembles the adult of another animal form, but only its embryo_" (p. 224).”
“Even the term embryo, which is officially correct, conjures images from the negative side, but really these are a ball of about 100 cells and they haven't become anything yet, and they've only been in the laboratory and frozen.”
“Some use the term embryo up to two or three months.”
“In humans, the term embryo is traditionally reserved for the first two months of development.”
“The destruction of the embryo is an additional crime, a second murder, at all events if we regard it as done with intent.”
“Abortion should be a last resort method and only to be used if the woman carrying the embryo is at risk.”
“Then you would know that after 8 weeks the embryo is then called a fetus and abortions are legal well past this stage.”
“Then you would know that after 8 weeks the embryo is then called a fetus and abortions are legal well past this stage. and your point is?”
“Wrong again, initially, the embryo is asexual, not female.”
“The lawsuit claims the embryo is a person who should be given equal protection under the Constitution, and her destruction violates her right to freedom from slavery.”
