Used to give a positive answer, agree with something, or accept an offer. The opposite of 'no'.

Interjection and adverb. Common extensions: 'yes, please' (politely accepting), 'yes, of course', 'yes, definitely'. Informal alternatives: 'yeah' (very common), 'yep', 'yup', 'aye' (Scottish/Northern English). 'Absolutely', 'certainly', 'of course' are more formal alternatives.

'Yeah' is the most common informal version of 'yes' in everyday British and American speech. 'Aye' is used in Scotland. In parliament, MPs vote by shouting 'Aye' or 'No' (not yes). 'Yes we can' was the famous campaign slogan of Barack Obama in 2008.
