This base type originates from Lat. ŭnctum ‘grease, ointment’ and correlates with the past participle of the Lat. verb ŭngere ‘to grease’. Due to nominalization, the meaning ‘the fat’ emerged. At the same time, it meant ‘ointment’ from the 2nd century on. Both meanings can still be found today. ‘Ointment’ is preserved in Ita. unguento, Piedmontese oit (cf. Treccani under unguento). A further component of this base is Ron. unt or Friulan ont with the meaning ‘Butter’ (cf. FEW 14, 29 under unctum; cf. REW 9057 under unctum. According to Kluge (2012: 437), the base type ancho appears to share the same Ine. root (*ongw en- ‛ointment, grease, butter’) with the base type ŭnctum.
