Definition

To make a serious promise, often using God's name, or to use rude or offensive language (bad words).

Usage & Nuances

Can be formal (promise/oath: 'I swear to tell the truth') or informal (using bad language: 'He swears a lot'). 'Swear' meaning 'use bad words' is very informal. Be careful: this word can sound strong or offensive depending on the context. Don't confuse 'swear in' (oath ceremony) with using bad language.
