Reattach → It is formed from "re-" (meaning again) and "attach" (from Old French *atachier*, meaning to fasten or join). The word "reattach" means to fasten or join something again after it has been detached.
Think of 'again' ('re-') when you fasten something ('attach') — that's why reattach means to fasten it again.
