(Less than intentional, more than accidental. I know the multiple meanings, so it came easily to mind by priming. That sort of unintentional wordplay is a bit of a bad habit, really, when it leads you to use obsolete vocab - the other day someone was asking me if I had made a typo for 'way' when I wrote 'X is in some wise deficient'. I didn't, but it's not like I was trying to be clear either.)
