Morphophonology is a subfield of linguistics that studies the interaction between morphology, the study of word structure, and phonology, the study of sound systems. It examines how changes in the form of a word, due to the addition of morphemes, affect its pronunciation, and conversely, how phonological processes can influence the form of morphemes. This means looking at how adding suffixes or prefixes can cause sounds to change, disappear, or be added within a word.

For instance, the pluralization of nouns in English often involves adding an /s/ sound. However, the pronunciation of this suffix varies depending on the preceding sound. After a voiceless consonant, like in 'cat', it becomes /s/ ('cats' /kæts/). After a voiced consonant, like in 'dog', it becomes /z/ ('dogs' /dɔgz/). And after sibilant sounds, like in 'bus', it becomes an extra syllable /ɪz/ ('buses' /bʌsɪz/). This variation is a classic example of a morphophonological rule.

Another area of study in morphophonology is allomorphy, where a single morpheme can have different phonetic realizations. For example, the past tense morpheme in English has three allomorphs: /t/, /d/, and /ɪd/, as seen in 'walked' /wɔkt/, 'played' /pleɪd/, and 'wanted' /wɒntɪd/. Morphophonology seeks to explain the systematic nature of these variations and how they are governed by underlying phonological and morphological principles. Understanding these interactions is crucial for a complete picture of how language works, from the smallest meaningful units to the sounds that make up spoken words.
