Synonym discussion

Sense: adverb/1

All four words describe motion or position that creates distance, but the angle differs. 'Off' focuses on leaving a surface or contact point — you step off a kerb, lift a lid off, or peel a label off. 'Away' is the broadest of the group: it just means 'to or at a distance', with no surface implied — you walk away from a friend, look away, throw rubbish away. 'Apart' stresses separation between two or more things that were previously joined or close together — pull the pieces apart, live ten miles apart. 'Aside' suggests a small sideways move so something is out of the main path, often temporarily — step aside, set the issue aside for later. 'Out' usually means leaving an enclosed space — walk out of the room, take the keys out. So you step off the train, walk away from the station, pull two carriages apart, move aside to let people pass, and climb out of the carriage.

Etymology

Proto-Indo-EuropeanProto-GermanicOld EnglishMiddle EnglishModern English

'Off' began life as the stressed pronunciation of Old English 'of', a preposition meaning 'away, from, out of'. For centuries the two were just spelling variants of one word. From around the early 1600s, English writers started using the spelling 'off' to mark the strong, motion-away meaning ('jump off the wall'), while keeping 'of' for the weak, unstressed senses of belonging and connection ('the lid of the box'). The original Old English root traces back to Proto-Germanic *aba and ultimately to a Proto-Indo-European root *apo- meaning 'away from', the same root behind Latin 'ab-' and Greek 'apo-'.
