re:What's wrong with viz.? It's been a while, but I'm pretty sure I knew what it meant when I was in secondary education. And I wasn't reading legal texts at that age, either.

yeah, but. we are self selected group here..

i got in trouble use N.B. on a document at work.. my manager with his master's degree (albeit a MS) didn't know what it meant, and thought it 'show off'. i learned N.B. in elemenatary school.

(but to be honest, i didn't now vide infra- i might have been able to guess it, or i would have looked it up. most dictionaries have common latin words/phrases in the appendix.)
