The dis- prefix, says Dictionary.com, is “a Latin prefix meaning ‘apart,’ ‘asunder,’ ‘away,’ ‘utterly,’ or having a privative, negative, or reversing force.” This is almost, but not quite, the opposite of ad-, and most of the dis- words I know sound funny with dis- thus replaced. In some cases, it’s more sensible to remove dis- entirely, as in the case of “disestablish.”
But can you be combobulated? (Or “accombobulated”?) Apparently combobulation is something you have to lose before you can gain:
Taking off your shoes and pulling out your laptop at airport security may leave you feeling discombobulated.
The Mitchell International Airport staff has set up some chairs and a sign just past one of the security checkpoints to help you out. They’ve labeled it the “recombobulation area.”
I can deal with that.
