In Hungarian, auxiliaries are conjugated as verbs (Lengyel 2000b: 252, Kiefer 2003: 212, É. Kiss 2002: 205‒229). Some auxiliary-like elements that express aspectual (e.g. szokott ‘used to’), pragmatic (e.g. tetszik ‘would be so kind as to...’) or modal (e.g. lehet ‘possible’, kell ‘must/have to’ cf. (5)–(6)) meanings have incomplete paradigms (Lengyel 2000b: 256‒257).
