IPA: /ɪmˈpɜːrmənəntli/
KK: /ɪmˈpɜrmənəntli/
In a way that does not last for a long time; temporarily.
The changes were made impermanently, so they could be reversed later.
Impermanently → It is formed from "in-" (meaning not) and "permanens" (from Latin, meaning lasting or enduring) and the suffix "-ly" (meaning in a manner). The word "impermanently" means in a manner that is not lasting or enduring.
Think of 'not lasting' ('in-') and 'enduring' ('permanens') to remember that 'impermanently' describes something that does not last.
