The Rule: Stress the second syllable before the suffix.
Examples: MOtivate, conGRAtulate, CALculate
Many learners of English stress the the -ate syllable. Even if the you add an -ed (EStimated) or -ing (EStimating) suffix, you wouldn't change the stress pattern. The only time you change the stress pattern is when you add an -ion suffix.
Listen to the examples:
EStimate |
EStimated |
EStimating |
EStimator |
estiMAtion |
INdicate |
INdicated |
INdicating |
INdicator |
indiCAtion |
Sometimes -ate words are adjectives, nouns and adverb.
adjective: That's an accurate description.
Noun: She is a graduate of Johns Hopkins
Adverb: Send the letter immediately.
The stress pattern is the same, but the -ate is pronounced differently. In nouns, adjectives and adverbs, the -ate is pronounced like "it".
Noun (ate= it) |
Verb (-ate=ate) |
