  • "to comprehend" is the Latin variant of the normal word "to understand". "to comprehend" is written elevated style.

According to the dictionary, comprehend simply means understand, but to me the connotations are slightly different. Comprehend seems more "comprehensive" --I would describe it as a deeper and more complete level of understanding.

I also see comprehend as dealing more with ability, the mental capacity to grasp something. For instance, I would say "I understand French, I comprehend physics." In terms of French, I either know what the words mean or I don't, it's (arguably) not a conceptual leap. For physics, I actually need to see the world in a different way.

You might say that a child comprehends a lesson, but only if it represents an actual conceptual advance, not just memorization.

You can.....

Comprehend is a verb that originates from the Latin word comprehendere, which means “catch or seize.”

  • When an idea is clear to you and you understand it completely, you comprehend it.
  • to take in or embrace; include; comprise.

.....Education is to help students understand the how's and why's. All complicated subjects need you to practice and think. Understanding requires knowledge and thought.

  • Another kind of understanding is like sympathy. For example, you might not approve of stealing, but you could understand why a guy would steal to feed his family.

  • Thanks for the Latin etymology. I'm reminded of the Biblical "the light shone in the darkness, and the darkness did not comprehend it," (John 1:5) where the term seemingly has connotations of understand, accept and overcome. Dec 23, 2014 at 16:24

I would say that they're more or less the same, however used in different contexts.

I comprehended a lesson

doesn't quite make sense for me; I would say that the differences are solely contextual.

I understood the lesson

Makes sense to me

However, note that it depends on what you mean by lesson: if you're talking about a lesson as in school, this would make sense, however if you are speaking of a lesson as in he's learned his lesson this wouldn't be appropriate.

    I would say that one can comprehend a subject, but understand a lesson. Dec 23, 2014 at 17:05
