Suffixes and Word Stress (2)
Unit 12; Part A
|In words with the following suffxes, main stress is usually on the syllable immediately before the suffix: -ial, -ic, -ion, -ive, and -ity. For example:|
When a word ends with one of the consonants t or s and the suffx -ion, this is how they are pronounced:
-tion is pronounced /t∫∂n/ afer the letter s: suggestion, digestion
/∫∂n/after other letters: education, adoption
-sion is pronounced /∫∂n/ after a consonant: extension, comprehension
/3∂n/after a vowel: decision, persuasion
-ssion is pronounced /∫∂n/ admission, expression
Unit 12; Part B
In nouns and adjectives ending with the suffxes -ant, -ent, -ance, or -ence, stress placement depends on the spelling of the syllable before the suffix (the pre-suffix syllable).
Unit 12; Part C
