Back in grammar, one of the many rules we were given was to always avoid "get," "got," or "gotten" due to their ambiguity and tendency toward poor grammar as in:
What happened to your arm? It got broke.
rather than
What happened to you arm? It was broken.
and
I got a ticket.
rather than
I have a ticket. or I purchased a ticket.
Is there still a respectable place for this abundantly overused verb (such as the passive mood, which, while generally to be avoided, can be used to convey an otherwise unobtainable feel in phrase)? Or is it ever condemned to literal taboo?
