"blameworthy, deserving to be censured," late 14c., from Old French reprehensible (14c.) and directly from Late Latin reprehensibilis "blamable," from reprehens-, past-participle stem of Latin reprehendere "to blame, censure, rebuke; seize, restrain" (see reprehend). Reprehendable in the same sense is from mid-14c. Reprehendatory (1853) was used in the sense of "conveying reproof." Related: Reprehensibly; reprehensibleness; reprehensibility.
