Root Breakdown

Root-derived
ento put into, to cause
+
ginebirth, produce, kind
=engine

From Latin ingenium, 'inborn talent, natural cleverness' (in- 'in' + gen 'born'). An engine was first any product of cleverness — a clever contrivance or device — long before steam. Over time 'ingenious device' shrank to 'machine.' The whole word is from the gen family; the spelling hides it.

Root gen still carries 140 more words

Why It Means This

Engine and ingenious are siblings: both come from ingenium, 'inborn cleverness.' Medieval war machines were called engines because they were clever inventions; the engineer was the person who built them. Only with the Industrial Revolution did engine settle on 'powered machine.' Modern metaphors (search engine, growth engine) revive the older idea: a clever device that drives things.
