Etymology: Solder is the older word here, and "re-" simply attaches to it to mean "again." Solder itself came into English from Old French "solder" (to make firm, fasten), which traces back to Latin "solidare," meaning to make solid, from "solidus," solid. So the verb "resolder" literally means to solder again: to rejoin or repair a metal joint that has failed or come apart. The prefix "re-" is one of the most productive in English, attached freely to verbs for repetition or restoration, which is why "resolder" needs no special history of its own. Its meaning follows directly from its two parts, with nothing shifted along the way.

Synonyms: rejoin, remelt, reweld
