Confusing words: convince, persuade
The verbs ‘convince’ and ‘persuade’ are very similar in meaning, but there is a difference in how we use them.
After ‘persuade’ we use the structure
to + infinitive:
- I persuaded them to stay for another drink.
- He persuaded her not to take the job.
After ‘convince’ we cannot use a verb infinitive. We say ‘convince someone that‘:
- She convinced the police that she was telling the truth.
- He convinced her that it was the right thing to do.
Both of the above sentence would also be correct without ‘that’:
There can also be a subtle difference in meaning between ‘convince’ and ‘persuade’, as seen here:
Although Robert finally persuaded his girlfriend to move abroad with him, she was not fully convinced that it was the best thing to do.
In the example, Robert’s girlfriend was persuaded (to move) but was not convinced (that it was the correct decision). So, we can see that when we persuade someone to do something it doesn’t always mean that we have also convinced that person.
One more thing is worth mentioning about ‘persuade’ and ‘convince’. If we are absolutely sure about something, we say I’m convinced:
– Are you sure he’s innocent?
– Yes, I’m convinced. NOT
