Verbalize comes from 'verbal' + '-ize'. 'Verbal' is from Latin 'verbalis', from 'verbum' ('word'), ultimately from Proto-Indo-European '*werh₁-' ('to speak'). The historical chain includes Latin verbalis, Latin verbum, and Proto-Indo-European *werh₁-. The quoted older senses, "verbal", "-ize", "Verbal", "verbalis", and "verbum", supply the semantic anchors for verbalize. The formation is best read as borrowed: the word verbalize carries its older form-history into a compact English lexical shape. In present English it is used as a verb, "to express something in words". English derivatives include verbalization; related English forms include verbal, verbalism, and verb. The result is a verb whose etymology preserves both the older form and the later English specialization.
