Pet form of Patricia or Patrick. It is generally a girl's name; as a boy's name it is almost completely restricted to Irish communities. Its popularity does not seem to have been seriously affected by its use in derogatory senses in the general vocabulary, in America meaning ‘a dupe’ and in Australia ‘a homosexual’. It is sometimes used as an independent girl's name.
Spanish: habitational name from any of the various minor places, for example in the provinces of Burgos, Guadalajara, and Valladolid, named from Spanish padilla ‘frying pan’, ‘breadpan’ (Latin patella, a diminutive of patina ‘shallow dish’), a word which was commonly used in the topographical sense of a gentle depression.
