adjective: being finicky about particulars. This needn't be a garbled tautology. Though being particular about something is the same as being finicky about something, a finicky person isn't necessarily particular about particulars, but about all kinds of vague, trivial nonsense not generally considered particular. A finicky person NEEDN'T fuss over minutiae, as it is up to his own discretion what to, or what not to, fuss over.

mind of the finicular person is debatable - whether it changes from a
general into a particular
state).
