Synonym discussion
Sense: adverb/1
All five words express agreement or acceptance, but they differ in tone and context. 'Yes' is the standard, neutral choice for formal and informal settings — used in job interviews, with strangers, and in polite conversation. 'Yeah' is the common casual spoken form; avoid it in writing or formal speech. 'Sure' sounds willing but slightly less committed than 'yes'; it often implies 'I don't mind' rather than strong enthusiasm. 'Of course' adds the idea that the answer is obvious or expected — useful when someone asks a favour, but it can sound dismissive if used for simple requests. 'Okay' (or 'OK') signals neutral acceptance, often used to acknowledge instructions rather than to show agreement. In a formal vote, only 'yes' (or 'yea') is used; in daily conversation with friends, 'yeah' is the most natural choice.

Etymology
The word 'yes' comes from Old English 'gēse' (ġēse), which is thought to be a contraction of 'gēa' (yea) + 'sīe' (third-person singular subjunctive of 'beon', to be). So its literal ancient meaning was something like 'yea, may it be so' — an emphatic affirmation. The spelling settled as 'yes' by the 1500s, replacing the older form 'yea' as the everyday affirmative in spoken English.
