Imbue implies the introduction of something that enters so deeply and so extensively into the thing’s substance or nature that no part is left untouched or unaffected; unlike infuse, which it otherwise closely resembles, imbue takes as its object the person or thing affected, not the thing that is introduced.

Ingrain is found in the. past participle or passive forms only; like imbue, it implies an incorporation of something comparable to a pervading dye with the body, substance, or nature of whatever is affected, but unlike imbue, it takes for its object or, when the verb is passive, as its subject the thing introduced rather than the person or thing affected.
