Surface Forms
Morphology
viviparity = viviparous (semi-transparent) = vivi + par + ity
Formed by a regular nominalization of the Latin-based stem (vivipar- + -ity), but the combining form 'vivi-' and Latin morphology are not common knowledge for average learners.
Etymology
Viviparity comes from the Latin parts vivi- 'alive' and parere 'to bring forth', the same roots you see in vivid and parent. So, for animals it means giving birth to live young instead of laying eggs.
