Verbs Ending in -ate

Approximately 1,000 English verbs end in the -ate suffix. These verbs are common in scientific, academic, and business contexts.

Listen to the following words. Can you figure out the rule for word stress in verbs that end in -ate?

illustrate

calculate

graduate

refrigerate

hesitate

investigate

negotiate

 

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

Tip

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)

He is going to give us an estimate.

He's going to estimate the cost.

She is a recent graduate.
