IPA: //nɒnˈɪntrəst//
KK: /nɑnˈɪntrəst/
Not related to or involving interest, especially in financial contexts.
The loan was offered on a noninterest basis, making it more affordable for borrowers.
Noninterest → It is formed from "non-" (meaning not) and "interest" (from Latin "interesse", meaning to be between or to matter). The word "noninterest" refers to something that does not matter or is not of concern.
Think of 'not' ('non-') being combined with 'matter' ('interest') — this helps you remember that 'noninterest' means something that does not matter.
