To comprehend something is to understand it, like when you have to read a difficult passage more than once in order to comprehend it.
When you comprehend something, you grasp its meaning. 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, like doing extra problems to make sure you comprehend a difficult algebra rule, or finding it hard to comprehend why someone would paint his house neon yellow.
