IPA: /əˌpriːʃiˈeɪʃən/
KK: /əˌpriːʃiˈeɪʃən/
A feeling of thankfulness or recognition for something good that someone has done.
She expressed her appreciation for the help she received during the project.
Appreciation is formed from "ad-" (meaning to) and "pretium" (meaning price or value) combined with the suffix "-ation" (indicating a process or action). The word refers to the process of recognizing or valuing something positively.
Think of 'adding value' ('ad-' means to and 'pretium' means price) to remember that appreciation means recognizing the worth of something.
