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.
For example, in English, the "p" sound in pot is aspirated (pronounced [pʰ]) while that in spot is not aspirated (pronounced [p]). However, English speakers intuitively treat both sounds as variations (allophones, which cannot give origin to minimal pairs) of the same phonological category, that is of the phoneme /p/.
Phonological awareness is an individual's awareness of the phonological structure, or sound structure, of words. [ 1 ] [ 2 ] [ 3 ] Phonological awareness is an important and reliable predictor of later reading ability and has, therefore, been the focus of much research.
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 ...
In Proto-Italic, for example, intervocalic */s/ became *[z]. It was a phonetic change, merely a mild and superficial complication in the phonological system, but when *[z] merged with */r/, the effect on the phonological system was greater. (The example will be discussed below, under conditioned merger.)
For example, the English vowel sound [æ], traditionally called the short A, in a word like mat (phonetically [mæt]), has the consonant [m] preceding it and the consonant [t] following it, while the [æ] itself is word-internal and forms the syllable nucleus. This all describes the phonetic environment of [æ].
A split in phonology is where a once identical phoneme diverges in different instances. A merger is the opposite: where two (or more) phonemes merge and become indistinguishable.
For example, the English suffix -s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs). [1] This type of assimilation is called progressive , where the second consonant assimilates to the first; regressive assimilation goes in the opposite direction, as can be seen in have to [hæftə] .
