So is pricking out seedlings and putting them in their own pots not called potting on? and if not, what is potting on? is it when they get too big for their pot and get moved to a bigger one?

In which case, if you single sowed in a small pot, and then moved the seedling to a bigger pot, would that be both pricking out and potting on at the same time? or is that called something else entirely?

The trouble I have is not enough pots or space to put them, even if I had some (otherwise I would just buy some!)
