Phoneme substitution is the correct term that accurately defines the practice of replacing one phoneme with another to form a new word. This process is a critical aspect of phonemic awareness, which is essential for developing reading and spelling skills in early childhood education. For example, changing the initial sound in "bat" to create "cat" is a clear demonstration of phoneme substitution.

This practice highlights the ability of children to recognize and manipulate sounds within words, which supports their overall literacy development. Engaging learners in phoneme substitution helps them better understand the relationship between sounds and letters, forming a foundational skill necessary for decoding and encoding words.

Options that refer to addition, deletion, or blending of phonemes do not convey the same process of replacing one sound for another, further emphasizing the specificity and importance of phoneme substitution in early literacy practice.
