Where does inclusion come from?
Borrowed from Latin inclūsiō, inclūsiōnis, from the verb Latin inclūdō (“to shut in, enclose, insert”), from in- (“in”) + claudō (“to shut”), ultimately from Proto-Indo-European *kleh₂w- (“key, hook, nail”). By surface analysis, include + -sion. Doublet of enclosure.
