unborn baby after early stage
A developing human or animal inside the mother’s body after the early embryo stage and before birth.
用法パターン：
a [fetus] develops in [the uterus]
よくある間違い：
Learners often confuse “fetus” with “embryo” or use them as exact synonyms. In medical English, an embryo is the early stage after fertilization, and a fetus is the later stage up to birth. Learners may also avoid the word and use only “baby,” which is fine in everyday speech but less precise in medical or legal contexts. Note the usual plural in modern English is “fetuses,” and the spelling “foetus” is mainly British and less common today.

embryo (Refers to an earlier developmental stage than a fetus; sometimes used loosely as a near-synonym, but medically distinct.)
対義語
adult (Represents the opposite life stage: a fully developed, born human rather than an unborn one.)
