IPA: //suːˈtɑːn//
KK: /sau'tæn/
A long, buttoned robe worn by priests, especially in the Roman Catholic Church.
The priest wore a soutane during the ceremony.
Soutane → The word 'soutane' comes from the Old French 'soutane', which refers to a long, formal robe worn by clergy. The term is derived from the Latin 'subtanea', meaning 'under garment', from 'sub-' (meaning under) and 'tunica' (meaning tunic). Thus, 'soutane' refers to a garment worn underneath or as part of clerical attire.
Think of a 'tunic' worn 'under' ('sub-') other garments — that's why a soutane is a long robe worn by clergy.
