Usage Note
Usar is fully regular (-ar). It is interchangeable with utilizar in most contexts, though utilizar sounds slightly more formal. The reflexive usarse appears in descriptions of custom or fashion: ya no se usa ('it's not done/worn anymore'). In Latin America usar also covers 'to wear' (clothing), a usage less common in Spain.
