​What do we call the underlying logic of the language,as opposed to the actual words of a sentence?

Quizplus · Accepted Answer

The underlying logic of a sentence, which includes the relationships between words and the overall meaning conveyed, is referred to as the deep structure. This is distinct from the surface structure, which refers to the actual arrangement of words and phrases within a sentence. Morphemes refer to the smallest units of meaning within a language (such as prefixes, suffixes, and roots), while phonemes refer to the individual sounds that make up words.
