The naming of doped semiconductors as "n-type" (for donor-doped) and "p-type" (for acceptor-doped) is ubiquitous. But I am having a hard time digging up where this naming tradition comes from and how it has come to be so widely accepted. From my perspective, there is nothing intuitive about this choice of notation. Henceforth the question:

Where does the tradition of labelling donor-doped extrinsic semiconductors as "n" and acceptor-doped as "p" come from?

For semiconductors, n-type mainly refers to Negative electrons which are the major charge carriers, whereas p-type refers to Positive, indicating holes which are the majority charge carriers (in this case), and can be thought of as positive.

In short, it tells us about the majority charge carriers in a particular type of semiconductor.

I want to supplement Eagle's answer.
Long before people deliberately doped semiconductors, physicists were studying samples of crystalline germanium.
While playing with these crystals, some seem to act as if they had a few n or negative carriers in them, and others seemed to have p or positive carriers in them.
At first it was not understood why they behaved this way, and the the naming convention long predates their use in electronics.
