It literally means "of the trivium" (grammar, logic/dialectic and rhetoric) , or, more broadly, that which can be arrived at by straightforward argument, without further specialized knowledge (covered in the quadrivium). It can, but doesn't necessarily, mean either easy or unimportant. Is identity merely unimportant, or is it also easy? Is a long chain of logic either easy or unimportant merely because it's trivial?
