Roman goddess of fertility, Latin Maia, literally "she who brings increase," from PIE *mag-ya- "she who is great" (suffixed form of root *meg- "great"). Maia, one of the Pleiades, is from Greek Maia, daughter of Atlas, mother of Hermes, literally "mother, good mother, dame; foster-mother, nurse, midwife," said by Watkins to be from infant babbling (see mamma).
