conceptual

The word 'conceptual' is built upon the noun 'concept,' which originates from the Latin past participle conceptus of the verb concipere, meaning "to take in, conceive, or form in the mind." This verb itself is a compound of con- (together) and capere (to take). The suffix -ual (from Latin -alis) was attached to form the adjective, a process common in Late Latin and Middle French. Thus, the literal meaning "relating to that which is taken together in the mind" evolved into the modern abstract sense of pertaining to mental constructs or ideas, distinguishing it from the physical or practical.

Structure: concept (idea) + ual (adjective suffix) - concept: From Latin conceptus (a thing conceived, idea, thought). The functional role is the core semantic root, carrying the meaning of "an idea formed in the mind." - ual: A suffix of Latin origin (-alis), used to form adjectives meaning "of, relating to, or characterized by" the root noun.
