In addition to being used to relay the exact words from another source, quotation marks can be used to convey misnomers and denote inaccuracies. If you write Her shirt looks interesting then that may be taken at face value. Her shirt looks “interesting” probably means that her shirt was, in fact, butt ugly. Though even more insulting would be Her “shirt” look interesting, indicating that what she was wearing could hardly qualify as a shirt at all.

See signs advertising “fresh” fish, a store that is Open 7 days “most of the time” and flowers with “delivery” available. See more examples below, after the jump; each photo is linked to its corresponding blog “post”.
