WORD HISTORY Nest is an ancient word, *nizdos in Indo-European, composed of the prefix *ni- "down," plus a form of the verbal root *sed-, "to sit," followed by a suffix used to form nouns, *-os. Thus a *ni-zd-os literally means "(place where the bird) sits down." In Germanic, an old zd became st. Thus *nizdos became *nistaz, which further changed in Old English to nest. Latin also inherited the word *nizdos from Indo-European, where it eventually changed to nīdus. This word has been borrowed into English as a scientific term. The prefix *ni- survives elsewhere in English, too, in the words beneath and nether.
