Single-letter words such as "a" and "I" can function as both phonemes (the smallest unit of sound) and morphemes (the smallest unit of meaning). In the case of "I," it can also function as a syntactic element, indicating the subject of a sentence. However, these single-letter words do not have independent semantic content, so they cannot be classified as both semantics and syntax.
