IPA: /ˈprɒf.lɪɡəsi/
KK: /ˈprɒf.lɪ.ɡə.si/
The act of wasting resources carelessly or extravagantly, often in a way that is considered immoral or irresponsible.
The profligacy of the government in spending taxpayer money led to public outrage.
Profligacy → It is formed from "pro-" (meaning forward or away) and "fligere" (meaning to strike down). The word describes a state of being recklessly extravagant or wasteful, as if one is striking down resources without care.
Think of 'striking down' ('fligere') resources 'forward' or 'away' ('pro-') — this helps you remember that profligacy means being recklessly wasteful.
