1. ostentatious in one’s learning.
2. overly concerned with minute details or formalisms, especially in teaching.
I can become preoccupied with minutia. My clothes are organized to such extent that I have five categories for shirts. Shoes are similarly ordered by like and kind. I find this not only the most efficient system, it is also aestetically pleasing in the extreme.
This happens perhaps even moreso with language.
And sometimes in my haste to expound, to correct, and clarify I make trifling grammatical errors. This is ironic.
