intellect vs intelligence

Speakers recalled Edwards as a woman filled with energy, intellect and humor. They joked they had trouble coming up with what to say without the woman who used to leave notes of advice for those close to her.

Can I replace "intellect' with "intelligence" in the above context?

I don't know what the difference between the two words even after looking up the dictionary. Could someone please elucidate it for me?

Thank you!

intelligence noun ( ABILITY )
n

Yes you can substitute the words. As far as the difference.......there is practically none. I can't think of an instance where you could not substitute those words one for the other except in the case of an I.Q. test. That is always an intelligence quiz. And it is said to measure intellignece, not intellect.

'intellect' means that this is a person who is thoughtful, thinks before she acts, and so responds to the world in terms of her intelligence(= her capacity to understand what is happening in any situation) - not a knee-jerk reaction based on her feelings or emotion.

Thank you both for your replies. 👁 Smile :)

The Internet is strewn with pages that explain the difference between intelligence and intellect.
There are so many that it is apparent to me, at least, that it is not possible to explain the difference, if there is any, concisely and simply.

Do the OED definitions help distinguish one from the other?

intelligence
1. The faculty of understanding; intellect.
3. The action or fact of mentally apprehending something; understanding, knowledge, comprehension (of something).
4. Understanding as a quality admitting of degree; spec. quickness or superiority of understanding, sagacity.

intellect
1.a. That faculty, or sum of faculties, of the mind or soul by which a person knows and reasons; power of thought; understanding; analytic intelligence; (also) an instance of this.

I don't think so 👁 Smile :)

...and that's why people post here: so that native speakers who have waded through it can try to explain the difference.
