IPA: /ɪnˈflɛksəbli/
KK: /ɪnˈflɛksəblɪ/
In a way that does not change or bend; showing no willingness to change one's mind or position.
She inflexibly refused to change her plans, no matter what anyone said.
Inflexibly → It is formed from "in-" (meaning not) and "flexibilis" (from Latin, meaning capable of being bent). The word "inflexibly" means not capable of being bent or rigid in attitude or behavior.
Think of 'not' ('in-') being able to 'bend' ('flexibilis') — that's why inflexibly means to be rigid or unyielding.
