Sense: verb/1
All four words describe touching someone with the lips as a sign of affection, but they differ in intensity, formality, and regional use. 'Kiss' is the neutral, all-purpose term — it covers every situation from a parent kissing a child goodnight to a romantic partner kissing on a date. 'Peck' refers to a quick, light kiss, usually on the cheek or lips, that lasts only a split second; it often signals a casual greeting rather than deep passion. 'Smooch' is an informal word for a longer, more romantic kiss involving sustained lip contact; you would use it in casual conversation but not in formal writing. 'Snog' is British slang for passionate, extended kissing, often while holding each other closely; it carries a stronger sense of intensity and is rarely used in American English. A parent might peck their child on the forehead before bed but would never snog them; romantic partners might start with a kiss and end up snogging on the sofa.

Etymology
The modern English word 'kiss' comes from the Old English 'cyssan', which itself traces back to the Proto-Germanic root '*kussijanan'. This root is shared with Old High German 'kussen' and Old Norse 'kyssa'. The word is ultimately thought to be of imitative origin — that is, it may echo the sound made by kissing. The noun form developed from the verb in Old English and has remained in continuous use for over a thousand years.
