IPA: /ʌnˈtɪpt/
KK: /ʌnˈtɪpt/
Describing something that has not been given a special tip or additional payment, often in the context of service or gratuity.
The waiter was disappointed because the customer left the meal untipped.
Untipped → It is formed from the prefix "un-" (meaning not) and the root "tipped" (from the verb "tip", meaning to tilt or to give a gratuity). The word "untipped" means not having been given a tip or gratuity, or not being tilted.
Think of 'not' ('un-') having been 'tipped' — that's why 'untipped' means something that hasn't received a tip.
