dictum

The word 'dictum' entered English in the late 16th century, directly from Latin where it meant "something said." It is the neuter past participle of the verb dicere, meaning "to say, speak, tell." This Latin verb itself is traced back to the Proto-Indo-European root deik-, which meant "to show, point out," a sense that naturally extended to verbal declaration. The logical evolution is from the physical act of pointing (PIE deik-) to the verbal act of stating authoritatively (Latin dicere), culminating in the modern English meaning of an authoritative pronouncement or an accepted principle, preserving the core idea of a formal utterance.

Structure: dict (say) + um (noun suffix) - dict: From Latin dictum (thing said), from the verb dicere (to say). It functions as the core root carrying the meaning of speaking or declaring. - um: A Latin neuter singular noun suffix, often used to form nouns from verb stems, indicating the result or object of the action.
