Sentence Stress and Weak Forms

There are a large number of words in English which can have a ‘full’ form and a ‘weak’ form. For example, compare the use of the word can and from in the following sentences:

She can / k ə n / swim faster than I can / k æ n /. (The first can is the weak form and the second is the full form.)
She’s from / f r ə m / Scotland. Where are you from / f r ɒ m /? (The first from is the weak form, and the second is the full form.)

As these words can be pronounced differently, it is important that learners recognize the possible forms of these words both when they listen and when they speak.
These words are most often the function words, filling in between content words, and making sentences ‘work’, grammatically.
The most frequently cited examples of these words are as outlined in the following table:

Keep in mind when learning weak forms that in certain positions, the full form is necessary. Also, at times, speakers may wish to emphasise function words for particular reasons:
no, I was coming FROM the station, not going TO it.

Weak forms are an important feature of ordinary, everyday speech, and learners should have the opportunity of becoming attuned to them. Learners should try to practise both strong and weak
forms and receive feedback on their production from a teacher in order to be able to produce the mix of strong and weak forms correctly, if they should wish.
