# What does it mean when a set is said to be a “finitely generated vector space”?

I've somehow managed to go through 3 years of my Maths degree without truly understanding what the term "finitely generated vector space" means.

Generated by what? Generating what? And for what? I have a very vague idea of what this term means and usually gloss over it when doing proofs but I think I just want a simple break-down of the meaning of this.

It means that the vector space has a finite generating set - that is, that a vector space $V$ has got a finite subset $\mathcal{B}$ such that $V = \text{span}\{b \in \mathcal{B}\}$. If the vector space is over a field, then this is equivalent to having a finite basis.
