An innocent word daydreams happily. Suddenly, the letter I barges in and sits next to it. The startled word gasps "If I'd have known I was coming!". The I squeezes in a "huh?!", but it's too late - a new word is formed.
The question body refers to both the shorter word and to the one with the I attached to it. The letter I may be added either at the start or at the end of the shorter word. The hints do not necessarily surrender the location.
The correct expected answer is the *long* word (i.e. the one with the I attached to it).
