Nest
NEST, the place where a bird lays its eggs, hatches them out, and shelters them until they are fledged. The word is used by analogy of other animals than birds, insects, etc. It appears in much the same form in Teutonic languages; related to it are Irish nead, and Lat. nidus, whence Fr. nid. It has been referred to the Gr. v6ar<K, return home, but it is now established that it represents a form nizdo- for nisido-, from ni-, down; cf. " nether," and sed-, to sit. Sanskrit has nida. The Lat. nidus has given the scientific term for nest-building, nidification (q.v.).
