Sense: verb/1
All four expressions describe preventing something from reaching you, but they differ in force and register. 'Fend off' is the most conversational — you fend off a punch, a question, or a cold using everyday actions like raising an arm or drinking tea. 'Repel' sounds more formal and often implies physical or scientific force, as in 'the fabric repels water' or 'the army repelled the attack'. 'Ward off' leans toward superstition or prevention, such as warding off evil spirits or illness. 'Keep at bay' is an idiom that emphasises holding a threat at a distance without eliminating it, like keeping your creditors at bay with small payments. Use 'fend off' in neutral everyday English; reach for 'repel' in formal or technical writing; use 'ward off' when the threat feels intangible or superstitious; and use 'keep at bay' when the danger remains but is temporarily controlled.

Etymology
The verb 'fend' is a shortened form of Middle English 'defenden', borrowed from Old French 'defendre', which in turn comes from Latin 'dēfendere' ('to ward off, protect'). The sense of a person managing alone ('fending for oneself') emerged in the early 1800s, shifting the focus from defending against an external threat to providing for one's own needs. 'Fend' lost its original prefix 'de-' over time, but its core idea of keeping something away — whether a blow or a problem — has remained constant since the 1300s.
