What key concept involves relationship between speech sounds and letters?

The correct choice is rooted in the understanding of how written language corresponds to spoken language through letters and sounds. Graphophonics refers specifically to the relationship between phonemes (the smallest units of sound) and graphemes (the written symbols representing those sounds). This concept is crucial in literacy development as it helps learners decode words and understand how letters can correspond to sounds in a language.

In the context of reading and writing, grasping graphophonics is essential for young learners and English Language Learners, as it aids in the development of spelling skills and reading fluency. By recognizing these patterns, students can more effectively translate their knowledge of spoken language into written form, enhancing their overall literacy skills.

Phonemic awareness focuses on the ability to hear, identify, and manipulate individual sounds in spoken words but does not specifically involve the written representation of those sounds. Semantic analysis deals with the meaning of words and phrases, while morpheme identification revolves around the smallest units of meaning in a language. Each of these concepts plays a role in language learning, but they do not directly address the letter-sound relationship that graphophonics encompasses.
