The rules are simple; you take the word above you and are allowed to change it in four ways. You can swap a letter for another (birds β bards), add a letter (word β sword), remove a letter (shimmer β simmer) or change a letter's place (deserts β dessert). You are also allowed to make up to three changes using any combination of changes you like (raptor β report β deportee β departed β retarded). As a tip: type the word in the reply box and edit it there.
And the starting word isβ¦
