[Tex/LaTex] Why \land instead of \and


I recently asked the logical and character in TeX and got \land as the answer. My question is, why \land, and why not simple \and? I mean, does l here refer to something technical, or historical, or stuff like that? Or is it simply there to prevent name clash. Do we have \and in TeX?

The names are the same that Knuth gave them in Plain TeX. Since \or and \not are already used for more important things, adding the prefix l for "logical" was almost natural, so "and" followed the convention. And LaTeX continues with it.

The symbols \land, \lor and \lnot have synonyms: \wedge, \vee and \neg as they are called, I guess, by some lattice theory specialists.
