IPA: //ʌnˈdjuː//
KK: /ʌnˈdu/
Exceeding what is normal or appropriate; excessive or not justified.
The committee decided to reject the proposal due to undue influence from outside sources.
Undue → It is formed from the prefix "un-" (meaning not) and the root "due" (from Latin "debere", meaning to owe). The word "undue" means not owed or not appropriate, often implying something excessive or unwarranted.
Think of 'not' ('un-') being combined with 'owed' ('due') — this helps you remember that 'undue' refers to something that is not appropriate or excessive.
