Stress in Longer Words 1
|We can build longer words by adding parts to the beginning or end of
shorter words. Usually, this does nor change the stress: it stays on
the same syllable as in the original word. Look at the example below.
Here is a list of beginnings and endings which do not change the stress of the shorter word:
|Some endings do change the stress in the shorter word. Look how the ending -ion changes the srress in the word educate.
|When we add the endings -ion or -ian, the stress always moves to the syllable before these endings. Here are some more examples.
|Note: -tion and -cian are pronounced /∫∂n/.|
|The ending -ic also moves the stress to the syllable before it. Listen to these examples.
Note: When a syllable changes from unstressed to stressed, or stressed to unstressed, the vowel sound often changes. For example the letter O in atom is pronounced /∂/, but in atomic, it is pronounced /o/, the A in atom is pronounced /æ/ but in atomic it is /∂/.
Note: The ending -al does not change the stress of the word (see A above), so, for example, the stress is on the same syllable in these two words: economic economical.
Use the beginnings and endings in A opposite to make longer words
from the words below. Listen and check if you get the same words as on
the recording. Then listen again and repeat.
|Write the words from the box in the correct part of the table according to the stress pattern.
Combine each word with one of the endings from the box, and give the stress pattern of your new word. You may need to change or add other letters to the first word. Use a dictionary to help you if necessary.
