Each word in the "ads" below can be changed into a new one by adding a single letter. The single letter is the same for all five words in that ad. The letter may be added at the beginning, middle, or end of the word, but no re-arrangement of letters is necessary. The resulting list of words isn't meant to make sense. For example, given the ad

FOR SALE: ROUND WINERY HEATER,
you would add T to each word to get
FORT STALE ROTUND WINTERY THEATER.
