Internalise → It is formed from "inter-" (meaning within) and "nal" (from Latin "internus", meaning inner) and the suffix "-ise" (meaning to make or to become). The word "internalise" means to make something part of one's inner self or to absorb it within oneself.
Think of making something part of your 'inner self' — 'inter-' means within, and 'nal' relates to the inner part.
