The act or result of appetizing; something that arouses or stimulates appetite.
From appetize plus the suffix -ment, which creates nouns from verbs describing the action or result. This follows the pattern of words like 'placement' (from place) and 'enticement' (from entice).
This is a beautifully constructed word that almost nobody uses anymore—we'd just say 'appetizer' instead. But 'appetizement' emphasizes the *action* of making someone hungry rather than the *thing* that does it. It's the difference between a noun and a process.
