finalmente
/fiˌnalˈmente/ · A2 · adv
lastly, finally, in the end
🏁 final + -mente (-ly) = finally; -mente turns adjectives into adverbs
Spanish builds adverbs by adding -mente to an adjective, just as English adds -ly. Final means final in both languages, so finalmente is literally final-ly. The same pattern gives normalmente (normally) and totalmente (totally).
