Common mistake
Common confusion with money: "I want to keep money for the trip" (retain/not spend it) vs "I want to save money for the trip" (accumulate it). Another error: saying "save this secret" — secrets are "kept", not "saved". "Keep a secret" is the fixed phrase.
Trick to remember it
Think of "save" as active (you accumulate, protect, rescue) and "keep" as passive (you simply hold on to it). "Save money" = active effort to accumulate. "Keep the money" = passive retention — don't spend it.
Quick rule
Save = accumulate / rescue / store. Keep = retain / hold on to.
Did you know?
"Keep" has over 30 phrasal verbs in English: keep up, keep on, keep out, keep off, keep away... It is one of the most productive verbs in the language. "Save" has fewer but includes "save up" (accumulate), "save face" (preserve dignity), and the computing term "save as".
