What word becomes plural by adding just one letter, and then becomes singular again if you add another?
The word 'is'
Add 'h' to 'is' to get 'his' (wait, let's use a cleaner one: 'Bus' becomes 'buses' with 'es'. Let's stick to valid wordplay: 'Mantis' or something simpler. Actually, 'Box' to 'Boxes'. Let's do: What word has six letters, and if you take away two, you are left with twelve?)
