I don't understand Ms. Still don't get it. Thought it's short for Miss.
Ms, Miss, and Mrs are all short for Mistress.
Does anyone else chose an unusual title if given a choice on a drop down list?
I do then when required for like online events or other unofficial things where it's a bit silly to require it so I'm going to be a bit silly too.
Titles being something everyone had is fairly recent, it used to be attached to profession, then class (and then, like all things to refer to women, it also got connected to prostituted women which is part of why we pronounce the abbreviation rather than saying Mistress as we say Mister or Master).
I think it's about time we return to them being optional rather than something we're required to have. I'm sure there are easier ways to manage the translating this type of information between countries for planes and such than using titles that not all countries use.
