New word order | 17 May 2018

In Competition No. 3048 you were invited to take an existing word and alter it by a) adding a letter, b) changing a letter, and c) deleting a letter — and to supply definitions for all three new words.
 
Inspiration for this challenge came from across the pond, courtesy of the Washington Post’s Style Invitational column, whose regular neologism-themed contests are always a blast.
 
Though many entries were partially successful, few competitors managed to score a bull’s-eye in all three sections of the challenge. A fiver per definition goes to those printed below who hit the spot with just one or two.
