Synonym discussion

Sense: verb/2

Patch is useful when damage is dealt with by adding a small extra piece, so the repair is local and often not complete. Mend is broader and often used for clothes or other small things that are made usable again. Repair is the most general choice and can describe larger, more careful work on roofs, machines, or walls. Darn is specific to sewing over holes in socks or sweaters with thread. Fix is the most everyday option, but it does not show how the object is restored. If Maya sews cloth over a torn knee, she patches the jeans. If a mechanic restores the whole engine, he repairs or fixes it rather than patches it.

Etymology

Middle EnglishEnglish

Patch appears in Middle English as pacche. Its earlier source is uncertain, but it may be related to older words for a small piece or marked spot. The earliest core idea was a bit of material used to mend damage. From that physical sense, English later developed wider meanings such as a marked area on a surface, a difficult period, and a small software fix.
