On this site, [rot13][1] is often used to encrypt comments so spoilers can be spoken about. Rot13 is a cipher, in which each letter is shifted 13 letters forward (or backward) in the alphabet.

There are certain words in the English alphabet which once rot13ed, form a new word. **Your task is to find the name for this type of word pair.**

The following sentences clue a pair. For instance, the sentence...

>’Muzzle the explosive.’ 

... would clue ‘gag’ and ‘tnt’, and rot13ing ‘gag’ gives ‘tnt’, and vice versa.

2.	Someone renouncing a non-existent place
3.	A grenade was delivered
