What is the process of changing one phoneme with another to create a new word called?

The process of changing one phoneme with another to create a new word is known as phoneme substitution. This linguistic concept involves replacing a single sound (the phoneme) in a word with a different sound, resulting in a new word. For example, substituting the initial sound in "bat" with /k/ would transform the word into "cat." This demonstrates how phonemes can be manipulated to alter meaning in language, showcasing the flexibility and creativity inherent in spoken and written communication.

The other options represent different phonological processes. Phoneme addition involves adding a phoneme to an existing word without substituting any sounds, phoneme blending refers to combining distinct phonemes to form a new word, and phoneme deletion consists of removing a phoneme from a word, which affects its pronunciation and meaning. Each of these terms captures different aspects of phonemic awareness, but phoneme substitution specifically focuses on the replacement of one sound to create a new word.
