aṇḍasū

 In Sanskrit, "aṇḍasū" (अण्डसू) refers to an oviparous animal—one that reproduces by laying eggs—and is a compound of "aṇḍa" (egg) and "sū" (producing or issuing).

Etymology and Linguistic Structure

The word "aṇḍasū" is a Sanskrit compound (samāsa) formed from:

• aṇḍa (अण्ड): meaning "egg"
• sū (सू): meaning "to produce," "to issue," or "beget"

Together, aṇḍasū literally means "egg-producer," describing an organism 

that lays eggs, i.e., an oviparous creature
