Other forms: inclusions
Inclusion is the taking in of somebody or something — the act of putting it inside a group, a list, a book. The inclusion of a vegetarian option on the menu, the inclusion of her name in the credits, the inclusion of one photograph that changes how the whole report reads.
It nearly always takes OF, and then IN: the inclusion OF something IN something. The social sense is the one you meet in schools, workplaces and policy documents, where inclusion means making sure nobody is shut out — ramps, subtitles, a class where every child sits in the same room. Its opposite is exclusion, and the two travel together in the same sentence. Jewellers use the word for something quite different: an inclusion is a speck of another mineral trapped inside a gem, and a diamond with fewer inclusions is worth more. The adjective is inclusive.

Latin inclūdō meant to shut in or enclose — in-, in, plus claudō, to shut, from a Proto-Indo-European root for a key or hook. Inclusion is literally the act of shutting something inside, which is why the modern social sense is really a question about who is allowed within the walls. Enclosure is the same Latin word arriving by another road.

Built from
Borrowed from Latin inclūsiō. Borrowed from Latin inclusio, 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. a doublet of enclosure.
