By A Vowel is a word jumble game. Each of the five words must be unjumbled — but each is missing one vowel. One word is missing an A, one is missing an E, one an I, one an O, and one a U.

Your task is to figure out each word, adding one vowel to each — but you can only add each vowel once.

Words may contain more than one vowel, but each is only missing one vowel.

There will always be a unifying theme behind the core words, ranging from subtle to not-so-subtle.

Words will turn green and "lock" if they are the correct core words. Words that turn blue are valid words that could work, but that aren't part of the puzzle's solution. Words in red aren't valid words. And words bordered in red indicate a vowel you used that you already used in a locked/correct green word. It sounds like a lot, but it's less confusing as you play.
