'Lavatory' is formal and emphasizes washing. 'Toilet' is direct and common in British English, but can be considered blunt in American English. 'Bathroom' (US) and 'loo' (UK informal) are the most common casual terms, though 'bathroom' in the UK implies a room with a bath.
It comes from the Latin 'lavare', meaning 'to wash'. Originally, it referred to a place for washing (hands, face, objects), and later became associated with the room containing washing facilities and a toilet.
No, 'lavatory' is exclusively a noun in modern English. Historical or technical uses like 'lavatory basin' exist, but 'lavatorial' is the adjective form, meaning relating to or resembling a lavatory, often used humorously (e.g., 'lavatorial humour').
