IPA: //ʌnˈsɪn.fəl//
KK: /ʌnˈsɪn.fəl/
Describing someone or something that does not commit sins or is free from wrongdoing.
The unsinful actions of the charity were praised by the community.
Unsinful → It is formed from "un-" (meaning not) and "sinful" (from Old English "synfull", meaning full of sin). The word "unsinful" means not full of sin or free from sin.
Think of 'not' ('un-') being added to 'full of sin' ('sinful') — that's why unsinful means free from sin.
