I know how to pronounce nota bene (YouTube can help if your Italian is rusty), but if you were reading an academic paper aloud (or something else that would contain notate bene), how would you go about saying "N.B." before continuing to read the note? Simply "note", or the proper "nota bene"?
You pronounce N.B. (also written as NB or n.b., nb) as
(MacMillan). See also Cambridge. In other words you say the names of the two letters, just like for e.g. (also eg) ( /ˌiː ˈdʒiː/). (MacMillan) You can also say Note or Note well, which parallels saying for example for e.g.
NB that the NB is from the Latin nota bene although the phrase is the same in Italian.
