Learn English – NSPF abbreviation

When I see "[sic]" after a word or phrase, I expect the sicced word to be obviously wrong, as in the M-W Online definition's example: Definition of SIC

"intentionally so written —used after a printed word or passage to indicate that it is intended exactly as printed or to indicate that it exactly reproduces an original (said he seed [sic] it all)"

Seeing a lot of "[sic]"s in a paper isn't pleasant. If you're talking about something like the Monty Hall problem, it's probably best to include a footnote or an explanation rather than a "[sic]". If there are a lot of paradoxical or incorrect statements in quoted material, then I'd use a superscript * to indicate that. If you're paraphrasing someone else and want to indicate errors, I'd also use some kind of footnote and superscript symbol if there are more than two.

I don't know of any abbreviation that meets your criteria, but you might try abbreviating verbatim as "(vbt)" if you really want an abbreviation instead of a superscript symbol + footnote combo.

Some airlines' tickets/boarding-passes use MSTR, e.g. from this travel website ...

MISS = Girl under 12 years,
MSTR = Boy under 12years,
INF = Under 2 years.
Please advise in special request, if you have flexible date

EDIT:
At one time at least, according to Wikipedia:

"Mstr" is [...] a prefix for boys on the UK Passport Service online application form. — Wikipedia

... however when I checked the UK website today, its current online form has a selection option with Master rather than Mstr! Note: the title does not appear on actual passport document, to avoid confusion I guess!

Update 13/Nov/2019: See https://travel.stackexchange.com/questions/149483/why-do-airline-tickets-have-titles-in-addition-to-names/149534#149534 which shows MSTR in use today on British Airways booking system.
