Tip 2: Learn how suffixes (= word endings) can change the stress patterns. Notice the following patterns when suffixes are added to words in English: No Stress Change
Word
manage /ˈmanɪʤ/ wonder category
/ˈwʌndə/ /ˈkatəgri/
+ Suffix
manager wonderful
/ˈmanɪʤə/ /ˈwʌndəfəl/
categorise /ˈkatəgərʌɪz/ No Stress Change, but Vowel Change Word
compete /kəmˈpiːt/ revise
/rɪˈvʌɪz/ produce /prəˈdjuːs/ + Suffix
competitor /kəmˈpԑtɪtə/ revision
/rɪˈvɪʒən/ production /prəˈdʌkʃən/
This produces “families” of words: photo /ˈfəʊtəʊ/
