1. Few uses mark out the Americanness of a person more readily than their natural use of
got and
gotten as alternative past participles of
get. (These uses are also spreading to Australia and New Zealand, as some of the examples given below will show.)
Gotten is no longer used in Britain (except in
ill-gotten), although it was once in regular use. In American English, it is used only when the meaning is 'have (or has) obtained or acquired', i.e. when it denotes coming into possession; when the meaning is 'have (or has) in one's possession', i.e. when it denotes the fact of possession now,
got is used. The difference can be seen by comparing the two sentences
We have gotten an apartment in Manhattan, which means we have recently acquired it, and
We have got an apartment in Manhattan, which means we have one available to us (as well as a house in Boston, for example). British English uses
got in both cases, with consequent ambiguity in some cases. Examples:
An army friend...had gotten us tickets for a Tchaikovsky extravaganza—Philip Roth, 1979
Have you gotten your paper the last couple of Sundays?—New Yorker, 1986
I'd only gotten about 4 hours of sleep the night before—weblog, Canadian English 2005 [Old English (up to 1150)C].
2. Gotten is also used when the meaning is 'have (or has) become, come, developed, etc.', i.e. when a notion of progression is involved:
Has my reputation in town gotten that bad?—T. Winton, Australian English 1985
This last year and a half I've gotten to fill out a lot of forms—John Updike, 1986
People in the USA have gotten much healthier in the past 30 years—USA Today, 1988
Many shipping companies have gotten rid of their nautical inspectors—Lloyd's List, 2001 (German speaker)
It's strange that I still haven't gotten used to it over the past fifteen years—fiction website, American English 2004.
3. Got, not
gotten, is used in the expression
have (or
has)
got to = must; for example, if you say
I have gotten to leave this evening you mean you have made arrangements to leave, not that you are obliged to leave.
