underwear
The Spanish word 'calzoncillo' translates directly into English as 'underwear'. This refers to a piece of clothing that is worn beneath exterior clothes, usually in direct contact with the skin, acting as a first layer of protection and hygiene. In context, it could be used in sentences like 'He is washing his underwear' which translates to 'El está lavando sus calzoncillos'. Both in English and Spanish, it can be used to refer to both the general category of such clothing, or to specific pieces within that category.
