Learn Finnish: Tämä ennennäkemätön ilmiö on oudompi kuin mikään muu. - This unprecedented phenomenon is stranger than anything else.

Even though mikään is typically used in negative sentences to mean "nothing", Finnish also uses it in certain affirmative contexts—like comparisons with kuin (than). In this structure, mikään translates to "anything" or "anything at all". If you used jotakin here, it would awkwardly imply the phenomenon is stranger than some specific, unknown thing, rather than anything else.

How do you break down the word ennennäkemätön (unprecedented)?

It is a compound word made of ennen (before) and näkemätön (unseen). Näkemätön is formed by taking the verb nähdä (to see) and adding the negative participle suffix -mätön, which creates an adjective meaning that something has not been done. Literally, the word means "before-unseen".

The dictionary word for "strange" is outo. Why does the "t" change to a "d" in oudompi?

This happens because of consonant gradation. Adding the comparative suffix -mpi closes the second syllable (ou-dom-pi). In Finnish, closing a syllable normally triggers the weak grade of a consonant, so the strong t in outo softens to a d.

Is the word muu strictly necessary at the end of this sentence?
