IPA: /ˌɪnəˈpriːʃəblɪ/
KK: /ɪnəˈpriːʃəblɪ/
In a way that is too small or insignificant to be noticed or measured.
The changes in temperature were inappreciably small, making no difference to the experiment.
Inappreciably → It is formed from "in-" (meaning not), "appreciable" (from Latin "appreciabilis", meaning able to be valued or estimated), and "-ly" (meaning in a manner). The word describes something that cannot be valued or estimated, often due to its smallness or insignificance.
Think of 'not' ('in-') being able to be 'valued' ('appreciable') — that's why inappreciably means something that cannot be valued.
