IPA: /ˌʌndərˈfaɪnənst/
KK: /ʌndərˈfaɪnæst/
Not having enough money or financial support to operate effectively.
The project was underfinanced, leading to delays and incomplete work.
Underfinanced → It is formed from "under-" (meaning below or insufficient) and "financed" (from the root "finance" which comes from Old French *financer*, meaning to provide funds). The word "underfinanced" means insufficiently funded or lacking adequate financial resources.
Think of being 'below' ('under-') the necessary 'funding' ('financed') — that's why underfinanced means not having enough money.
