fetusn.

Brit.

/ˈfiːtəs/, U.S.

/ˈfidəs/

Inflections: Plural fetuses, (rare) feti.

Forms: Middle English– fetus, 1600s– faetus, 1600s– foetus.

Origin: A borrowing from Latin. Etymons: Latin fētus, foetus.

Etymology: < classical Latin fētus (also foetus: see note) (-u- stem) bringing forth of young, parturition, breeding, conception, offspring, young while still in the womb < the same Indo-European base as classical Latin fēmina woman (see female adj.) + -tus, suffix forming verbal nouns.Compare Middle French fetus , Middle French, French fœtus (1478; c1370 as fete ), Spanish feto (1493), Italian feto (a1321); also Middle Dutch fetus (c1490 in an apparently isolated attestation; Dutch foetus subsequently from 1658), German Fötus (1703, in early use with Latin inflectional endings). In Latin manuscripts both fētus and foetus are used; in inscriptions only fētus . The spelling variation may be due to analogy with similar variation in words that historically showed -oe- , e.g. amoenus , amenus amene adj. The plural form feti is formed by analogy with Latin nouns of the second declension ending in -us.

1. Originally: the offspring of a human or other animal during its development within the uterus or egg. In later use: spec. the developing offspring of a human or other viviparous animal in the period after the major structures of the body have been formed. Cf. embryo n. 1.In humans, the transition between embryo and fetus is now usually taken to have occurred by the end of the eighth week of gestation.
