Morphology
rpm = R + P + M
An initialism for 'revolutions per minute' whose meaning is not recoverable by most learners from the letters alone; it is a specialized abbreviation.
Etymology
Rpm stands for revolutions per minute, where revolution means a full 'turn' and minute means one 'minute' of time or 60 seconds. So rpm tells you how many full turns an engine or wheel makes in one minute, which is why it measures speed.
