+This exercise is tricky and was removed from our recommendations because it mostly leverages regular expressions for the solution, and those aren't really taught at this point in our curriculum.
+
+Leaving it here for posterity, or a good challenge for anyone that wants to give it a shot.
+
+Pig Latin is a children's language that is intended to be confusing when spoken quickly. Your job for this exercise is to create a solution that takes the words given and
+turns them into pig latin. Please see the following wikipedia page for details regarding the rules of Pig Latin:
+
+https://en.wikipedia.org/wiki/Pig_Latin
+
+The rules section will give the rules and the examples that are required to complete this exercise.

+//  Pig Latin
+
+// Pig Latin is a made-up children's language that's intended to be confusing. It obeys a few simple rules (below) but when it's spoken quickly it's really difficult for non-children (and non-native speakers) to understand.
+
+// Rule 1: If a word begins with a vowel sound, add an "ay" sound to the end of the word.
+
+// Rule 2: If a word begins with a consonant sound, move it to the end of the word, and then add an "ay" sound to the end of the word.
+
+// (There are a few more rules for edge cases, and there are regional variants too, but that should be enough to understand the tests.)
+
+// See https://en.wikipedia.org/wiki/Pig_Latin for more details.
