IPA: /nɒnˈfaɪnænʃəl/
KK: /nɑnˈfɪnənʃəl/
Not related to money or financial matters.
The report included both financial and nonfinancial information.
Nonfinancial → It is formed from "non-" (meaning not) and "financial" (from Latin "financia", meaning relating to money). The word "nonfinancial" means not relating to money or finance.
Think of 'non-' meaning 'not' and 'financial' relating to money — so nonfinancial refers to things that are not about money.
