Unit 15. 'Subway and 'Super,power.

Prefixes and Word Stress (2)

Unit 15; Part A

In some words with prefixes, the prefix itself is stressed. Most of these words are shown as having main stress on the prefix and, in some cases, secondary stress later in the word:
       subway    /'sΛbweι/    superpower    /'su:p∂,pau∂r/

Most words like this are nouns and include:





In these words the syllable with main stress usually has prominence in discourse:

       We took the SUBway.    I'm j ust off to the SUpermarket.

Unit 15; Part B

However, other words with these prefixes have main stress on a syllable afer the prefix. Most words like this are adjectives and include:




In these words the syllable with main stress usually has prominence in conversation:

         They have to learn to co-eXIST    The climate here is subTROPical.

but prominence may go on the syllable with secondary stress in some cases
(see C).

Unit 15; Part C

In many words with a prefix, there is secondary stress on the prefix, with main stress later in the word:
      ,impre'cise             ,disa'gree             ,hyper'active
When these words are used in conversation they can have stress shift (see Unit 10B), with the prefix made prominent rather than the main stressed syllable. Compare:
      Her answer was impreCISE.    but:  She gave an IMprecise ANswer.
     He's hyperACtive.    but:   I work with HYperactive CHILdren.
     He disaGREED.   but:  He DISagreed STRONGly.
Here are some more words with prefixes which commonly have stress shift: ,decom'pose  ,de'code  ,diso'bedient  ,disre'spectful  ,imma'ture  ,impo'lite  ,mis'place   ,mis'spelt   ,recon'sider  ,repro'duce   ,unac'ceptable   ,unsuc'cessful

However, some other words with these prefixes rarely have stress shift, including: de'fame  dis'honest  im'practical  ,mis'judge  re'place  un'popular.
