Forms

lēgitimō (present infinitive lēgitimāre, perfect active lēgitimāvī, supine lēgitimātum); first conjugation[1]

Etymology

It is a medieval formation from Latin lēgitimus (“lawful, legitimate”) + -ō,[1][2] ultimately from lēx (“law”).[3][4]

Earliest recorded meaning

Köbler finds it first in Gerhard of Augsburg, 983–993,[3] meaning to endow with dotal land and to legitimize.[3]

Semantic evolution

Niermeyer records two senses: providing a church with a glebe, and legitimizing a son or daughter.[5] British sources use it more broadly for confirming a person or a thing by law (1305), and for making a child born out of wedlock legitimate, as in a text of 1232.[2] Du Cange glosses it as giving a bastard the rights of one born in lawful marriage, and compares French légitimer and Spanish legitimar.[6] In Hungarian charters from 1292 on it means to legitimize persons or confirm things.[7]

English legitimate comes partly from Old French legitimer, partly directly from the Medieval Latin participle legitimatus.[4]
