(pl. fetuses)
- an unborn or unhatched offspring of a mammal, in particular, an unborn human more than eight weeks after conception
（尤指受孕八周后的）胎儿
- late Middle English: from Latin fetus 'pregnancy, childbirth, offspring'
- The spelling foetus has no etymological basis but is recorded from the 16th century and until recently was the standard British spelling in both technical and non-technical use. In technical usage fetus is now the standard spelling throughout the English-speaking world, but foetus is still found in British English outside technical contexts
