Engrain is formed from "en-" (meaning to cause to be in) and "grain" (from Old French *grain*, meaning seed or small particle). The word "engrain" means to cause something to be deeply embedded or ingrained, like a seed taking root.
Think of 'causing something to be in' ('en-') like a 'seed' ('grain') taking root deeply in the ground — that's how ingrained something becomes.
