IPA: //ʌnˈɡɒdliə//
KK: /ʌnˈɡɑdliər/
More immoral or wicked than others; lacking in reverence for a deity or divine principles.
His actions were ungodlier than anyone could have imagined.
Ungodlier → It is formed from the prefix "un-" (meaning not) and "godly" (from Old English *godlic*, meaning divine or godlike) and the suffix "-er" (meaning more). The word "ungodlier" means more not divine or less godlike.
Think of 'not' ('un-') being added to 'divine' ('godly') to remember that 'ungodlier' means more lacking in divine qualities.
