Chapter 5 in “The Study of Language” by Yule is about the sound patterns of language. First is explained the term phonology, which describes the patterns of speech sounds in a language. The phonology helps us to distinguish the meaning in sounds that we hear and say. The phonemes /f/ and /v/ in English language help us to distinguish the meaning between the words fat and vat, this meaning in a sound is described as a phoneme. In a regular speech one sound can be pronounced with many different versions. Those different versions are called phones. When there are many versions of one phoneme then those versions are called allophones. It is interesting that when we pronounce the word tar, the puff of air, called aspiration is stronger. For a difference when we pronounce star, the puff of air is weaker (pg.45). When replacing one phoneme for another in a word, then the result is a different meaning and different pronunciation, for a difference replacing one allophone for another, the result is only a different pronunciation of the same word. Then in this chapter is explained the term minimal pair, which means two words fan-van are identical in form, except for a contrast in one phoneme. A minimal set is when group of words can be differentiated by changing one phoneme such as fit, fate, foot, fought. Phonotactics are part of every speaker’s phonological knowledge; they are permitted arrangements of sounds. The basic elements of the syllable are the onset and the rhyme. The onset consists of one or more consonants, and the rhyme consists of vowel, called nucleus and consonant, called coda. When we pronounce English words in everyday speech the assimilation process takes place. The same process happens in Macedonian language. This process happens because is easier and quicker (pg.49).
