KK: /ʌnˈɡreɪtfəli/
In a way that shows a lack of appreciation or thankfulness.
She ungratefully accepted the gift without saying thank you.
**Ungratefully** → It is formed from "un-" (meaning not) and "grateful" (from Latin *gratus*, meaning pleasing or thankful) and the suffix "-ly" (meaning in a manner of). The word "ungratefully" means in a manner that is not thankful or appreciative.
Think of 'not' ('un-') being combined with 'thankful' ('grateful') to remember that 'ungratefully' describes acting in a way that lacks appreciation.
