Paronomasia is the fancy word for a pun.  A pun is intentional wordplay, unlike a malapropism (see yesterday’s post).  An eggcorn is in the same family as the pun and malapropism, but differs slightly from both.  One example of an eggcorn would be mistakenly saying “old-timers’ disease,” instead of “Alzheimer’s disease.” But unlike a malapropism where the new sentence is nonsensical, an eggcorn still makes a little sense, as is the case with Alzheimer’s… The linguistic example, of course.  Not the actual disease…
