A quote in a book contained the word "con[struction]."
It was used just as the word construct would have been. Is con ever used as an abbreviation of construction? Would there be any other reason to complete the quote like that?
Unfortunately I can't quote the context; I lost the bookmark, I don't remember the page, and I lack a searchable copy. I do remember that the quote was not weird in any other way, and that there was no apparent reason to do this. The book in question is Neal Stephenson's Cryptonomicon. The word might have been "con[truct]".
