discreditable

The word discreditable is a relatively modern English formation, built upon the established noun "credit," which entered English from Latin via French with meanings related to belief, trust, and financial reputation. The negative prefix dis- is attached to reverse the sense, creating the concept of "damaging to credit or reputation." Finally, the adjectival suffix -able is added, shifting the meaning to "capable of causing such damage." Thus, the literal morpheme logic "capable of removing trust" evolved neatly into the modern abstract sense of "disgraceful" or "harmful to one's good name."

Structure: dis (opposite) + credit (trust, reputation) + able (capable of) - dis: A Latin prefix meaning "apart," "asunder," "away," or having a negative or reversing force. - credit: From Latin creditum (a loan, thing entrusted), from credere (to trust, believe). In this word, it functions as the base meaning "trust" or "reputation." - able: A suffix of Latin origin (-abilis) via French, meaning "capable of, fit for, or worthy of being the object of an action."
