What does unalterably mean?
Unalterably is an adverb meaning in a way that cannot be changed, altered, or reversed. It is used when an action, decision, condition, or commitment has a final, permanent character: a treaty may be described as unalterably binding, or a person’s principles as fundamentally opposed to compromise. The word is more emphatic than permanently because it focuses on the impossibility of later alteration rather than simply the duration of something. In formal writing, irrevocably can often do similar work, while unalterably has a more categorical tone. Because it is relatively uncommon, it is especially effective when precision matters or when the permanence of a situation deserves emphasis. It normally appears as an adverb and should not be confused with the adjective unalterable, which describes something itself incapable of being changed.

The prefix un- locks the door: if something is unalterably fixed, “alter” is exactly what cannot happen.

Where does unalterably come from?
The word was formed in English by adding the negative prefix un- to alterable and then changing the adjective into the adverb -ly. Alterable belongs to a wider family of English words derived through Old French and Latin from Latin alter, meaning “other”; related forms include alternate, alternative, and alteration. The modern formation expresses the idea that something cannot be altered.
