Help me understand the Student's t-distribution.

I've studied it but I don't remember it.

Of course, I do want to understand the procedure to use when trying to estimate the variance of a population from a single sample. I understand that this is its main use.

But I mainly want to have a terse, but 100% conceptually crisp, understanding of the key concepts necessary to understand why this procedure is what it is. FOr me to remember things, it is important that they be very coherent. So I care a lot about precision in terminology, e.g., to distinguish what is treated as a random variable, what is a parameter of a distribution, over what range of values an expectation is calculated, etc..
