IPA: //ˈɡrʌntəld//
KK: /ˈɡrʌntəld/
Feeling satisfied or pleased about something.
After receiving the good news, she was quite gruntled.
Gruntled is derived from the past participle of the verb 'gruntle', which is a variant of 'grunt', meaning to make a low, guttural sound. The prefix 'dis-' (meaning not) is often mistakenly associated with the word, but 'gruntled' actually means to be in a state of contentment or satisfaction, as in being 'gruntled' is the opposite of being 'disgruntled'.
Think of the sound 'grunt' as a sign of satisfaction or contentment — when someone is 'gruntled', they are in a good mood, unlike when they are 'disgruntled'.
