What are elisions and transpositions classified as in phonological processes?

Elisions and transpositions are classified as manipulations in phonological processes because they involve specific changes to the structure of phonemes within a word or phrase.

Elision refers to the omission of certain sounds in speech, often resulting in a simplification of pronunciation. For example, in rapid speech, the word "comfortable" may be pronounced without the middle syllable, becoming "comfy" or "cumpfort." This process manipulates the sound structure to make speaking easier and more fluid.

Transposition involves rearranging sounds or syllables within a word. An example can be found in the common occurrence of reversing the sounds in "ask" to produce "aks." This manipulation alters the order of phonemes to create a variation in pronunciation.

Both processes involve actively changing the way sounds are articulated, which is why they fall under the category of manipulations. This focus on modifying phonological structure sets them apart from additions, blending, and deletions, which involve other types of phonetic or phonological changes.
