Doler is a fairly common verb (and, like many everyday verbs, it's conjugated irregularly, in the same way as mover is) that is used to say that something is hurting a person or otherwise causing pain. Doler can be confusing for beginning Spanish students who forget that it usually requires a different sentence structure than what they are used to, although its use is very similar to that of gustar.

I am reading your explanation on caer and caerse and am interested to know if you have addressed morir and morirse. Not being a native speaker, those two verbs are very confusing for me and my students.

The quick answer is that this is one of those cases where there isn't much difference — both verbs mean "to die." As explained in our new lesson on morir and morirse, the reflexive morirse may be more informal and maybe even a bit more respectful. Morir may be the safer choice if you're not sure which to use — just make sure to conjugate morir correctly!

When you're talking about when something is going to happen, you don't always need to know the exact time. Often, a time of day like morning or evening is sufficient. Our newest lesson, on times of the day, lists the most common possibilities.

Tan and tanto are obviously related to each other, and they are both used in making what are known as comparisons of equality. However, they are not used the same way: Tan is used with adverbs and adjectives, while tanto (and its variations) is used with nouns.
