I'm looking for a phrase or word that basically means interchangeable with other parts.


I'm working on a proposal in which I'm describing a technical solution that consists of several parts which can be connected to other technical solutions (kind of like a connector set). I think there's a good word for this, but I can't seem to remember what that word is. I almost feel like it's on the tip of my tongue, but I just can't come up with a single word (or concise phrase might do). Thanks.

    Could you supply a sample sentence (probably as part of the "Need" section) please?

    Modules maybe? Really hard to tell. Give us the sentence, and ideally the whole paragraph. Failing that, the best word for "interchangeable" is, well, interchangeable. Whether it's parts or cats or planets, that's the word alright.

  • You're not thinking of compatible?

I'd go with modular. For instance, for a modular smart phone the user himself can choose to install modules like cameras, ports, and such.

modular (from Wiktionary, 2019):

Consisting of separate modules; especially where each module performs or fulfills some specified function and could be replaced by a similar module for the same function, independently of the other modules.
