REDUCTION
Reduction is a historical process of weakening, shortening or disappearance of vowel sounds in
unstressed positions. This phonetic phenomenon, as well assimilation, is closely connected with the
general development of the language system. Reduction reflects the process of lexical and
grammatical changes.
Reduction is realized:
a) in unstressed syllables within words, eg. demonstrative
b) in unstressed form-words, auxiliary and modal words, personal and possessive pronouns
within intonation groups and phrases, eg. What do you think you can do? (Weak forms)
Three different types of reduction are noticed in English:
1. Quantitative reduction, i.e. shortening of a vowel sound in the unstressed position,
affects mainly long vowels, eg [hi: - hiJ - hI].
When does he come? [→wen dΛz hI ˛kΛm].
2. Qualitative reduction, i.e. obscuration of vowels towards [ə, Ι, υ ], affects both long and
short vowels, eg can [kæn – kən].
You can easily do it. [ju kən → i:zIlI ˛du: It].
Vowels in unstressed form-words in most cases undergo both quantitative and qualitative
reduction, eg [tu: – tu - tυ].
3. The third type is the elision of vowels in the unstressed position, eg I’m up already
[aIm Λp ˛o:lredI].
Strong forms
1. Strong forms
Prepositions:
a) at the very end of an intonation group or phrase;
b) at the end of an intonation group or phrase when they are followed by the unstressed pronoun.
Auxiliary and modal verbs:
a) at the end of an intonation group or a phrase whether stressed or not.
b) at the beginning of general and alternative questions in careful colloquial style, while in rapid
colloquial style they are unstressed and reduced.
c) in contracted negative forms.
to have
the verb to have has no weak form in the meaning of ‘to possess’.
eg. I have a little brother.
Demonstrative pronouns:
The demonstrative pronoun is never reduced while the conjunction that is,
eg. I know that
But I know that he is here.
Possessive pronouns:
The absolute forms of possessive pronouns is never reduced, eg. The ball-pen is mine.
What, where, when, how, which, on, in, with, then have no weak forms.
All the form-words, auxiliary and modal verbs, personal and possessive pronouns are generally
stressed and consequently have their strong forms in case they become the logical centres of phrases.
Comparison with Russian
Russian speech is characterized by different rhythmical structure. Personal and possessive
pronouns, auxiliary and modal verbs are often stressed in Russian.
Mistakes of Russian Learners
Russian students of English replace strong forms by weak forms in places where there should be
no reduction in the unstressed position.
