Studies show that the average person can speak up to 125 words a minute, but could be able to process up to 500 words a minute when listening.


In the above quote, could is right? If it is right, why do the different tenses use? I'd like to know what is the means of could be able to?

Thank you.

I don't think that "could" is a good choice in that sentence. I would say "..............but (is able to)(can) process...........'. You can choose 'is able too' or 'can'.

"Could" means "would be able to," so "could be able to" means "would be able to be able to," and that's not good English.

2006 & CP -

I really enjoy reading your posts. Your explanations are very clear and I

learn something new about the language every time I have a chance to

visit this forum.

Thanks - Philo
