the word vaporize is a modern english formation, built upon the latin noun 'vapor', meaning steam or exhalation. this latin term is of uncertain deeper origin, though it may be related to concepts of warmth and emission. the suffix '-ize', derived from greek '-izein' via latin '-izare', is a prolific verb-forming element meaning 'to make or become'. therefore, the literal construction 'to make into vapor' perfectly captures the word's core meaning of converting a substance into a gaseous state. this logical, compositional etymology directly informs its scientific and figurative uses today.

Structure: vapor (vapor) + ize (to make) vapor (latin origin, meaning 'steam, exhalation', functions as the core noun root); ize (greek origin via latin and french, a verb-forming suffix meaning 'to make, to become', functions as a derivational suffix)
