⚙️ funcionamiento = función (function) + -miento (the act of) → the act of functioning
Built from Spanish función, 'function', plus the noun suffix -miento, which names an action or result. So funcionamiento is the way something carries out its function: how it works. Compare English 'function' and 'functioning'.
