Im playing the Adjective word game.. the words are:

Tough, Many, Enthusiastically, Under, Evil, Frantically, Great, Since, These, Kissingly, Never, Much, Beyond, Nobody, Others, Up, Frantically, Never

Now i chose "Evil, Tough & Slowly".. Why is slowly not an Adjective ?

I cant get my head around why it isnt one. Can anyone explain ?

A sentence: "He moved slowly through the forest" is not slowly a descriptive word ?
