What aspect of linguistics studies the relationship between written symbols and their pronunciations?

Graphemics is the aspect of linguistics that focuses on the study of written symbols and their correspondence to sounds or pronunciations in a language. This field examines how individual letters, characters, or graphemes represent phonemes, which are the smallest units of sound in speech. By understanding graphemics, linguists can analyze how written language is constructed and how it relates to its spoken form, thus enabling learners to better understand the connections between reading and phonetic pronunciation.

The other options do not pertain specifically to this relationship. Lexical studies focus on the vocabulary of a language and the meanings of words, rather than their written forms or pronunciations. Syllabic analysis centers on the structure and patterns of syllables within words, but it does not primarily address the relationship between written symbols and their spoken equivalents. Grammar deals with the rules and structure of language, including syntax and morphology, but it does not focus solely on the connection between writing and pronunciation. Therefore, graphemics is the correct choice.
