interalie

The whole thing is the word. You can see inter and you can see alie inside it, and both readings are honest: inter is the ordinary preposition "among", and alie is the -e adverb of alia, "in another way, otherwise". But alie has no page of its own on this site, and that is not an oversight - it is the point. What learners actually meet in running Esperanto is the welded whole, interalie, in exactly the slot English uses "among other things". The parts are transparent; the meaning is fixed by convention rather than assembled fresh each time, so the lexicalised whole is the lemma and the page.

It behaves like a comment, not like a verb argument. Interalie drops into a sentence between commas, or leans directly on the phrase it qualifies: Li menciis interalie la koston - he mentioned, among other things, the cost. It is signalling that your list is not exhaustive, which is a politer and more precise move than it looks: it tells the reader there is more, without pretending to give it.

The connector family. Aliflanke (on the other hand) is built the same way, from the same ali- root, and is the closest sibling. Around them sit cetere (besides, by the way), precipe (especially - the opposite move, narrowing rather than widening), tamen (however) and plain ankaŭ (also). Learn them as a set: they are the joints an essay turns on, and Esperanto gives you all of them for the price of a handful of roots.
