IPA: /ɪnˈɛkspɪdiənt/
KK: /ɪnˈɛkspɪdiənt/
Not advisable or practical; not suitable for achieving a desired outcome.
Choosing to ignore the warning was an inexpedient decision that led to problems later.
Inexpedient → It is formed from "in-" (meaning not) and "expedient" (from Latin "expedire", meaning to free or to make ready). The word "inexpedient" means not suitable or not advisable for a particular purpose or situation.
Think of 'not' ('in-') being combined with 'making ready' ('expedient') — that's why inexpedient means something that is not suitable or advisable.
