A phonological rule is a formal way of expressing a systematic phonological or morphophonological process in linguistics.Phonological rules are commonly used in generative phonology as a notation to capture sound-related operations and computations the human brain performs when producing or comprehending spoken language.
Phonology also includes topics such as phonotactics (the phonological constraints on what sounds can appear in what positions in a given language) and phonological alternation (how the pronunciation of a sound changes through the application of phonological rules, sometimes in a given order that can be feeding or bleeding, [16]) as well as ...
The following table shows the 24 consonant phonemes found in most dialects of English, plus /x/, whose distribution is more limited. Fortis consonants are always voiceless, aspirated in syllable onset (except in clusters beginning with /s/ or /ʃ/), and sometimes also glottalized to an extent in syllable coda (most likely to occur with /t/, see T-glottalization), while lenis consonants are ...
Until the 1950s, many phonologists assumed that neutralizing rules generally applied before allophonic rules. Thus phonological analysis was split into two parts: a morphophonological part, where neutralizing rules were developed to derive phonemes from morphophonemes; and a purely phonological part, where phones were derived from the phonemes.
Bleeding order is a term used in phonology to describe specific interactions of phonological rules. The term was introduced in 1968 by Paul Kiparsky. [1] If two phonological rules are said to be in bleeding order, the application of the first rule creates a context in which the second rule can no longer apply.
The phonological component of each lexical entry is considered to be a linear sequence of these feature bundles. A number of context-sensitive rules transform the underlying form of a sequence of words into the final phonetic form that is uttered by the speaker. These rules are allowed access to the tree structure that the syntax is said to output.
In phonology and historical linguistics, feeding order of phonological rules refers to a situation in which the application of a rule A creates new contexts in which a rule B can apply; it would not have been possible for rule B to apply otherwise. Suppose there are two rules. Rule A takes in input x and returns output y.
The rules described above did not apply to the fricatives /x/ (spelled h ) or /ʃ/ (spelled sc , often written sċ in modern editions). In contexts where other fricatives became voiced, Proto-Germanic * x came to be lost entirely in Old English, though before it was lost it caused certain sound changes such as breaking of preceding vowels.
