I found myself writing the word "earlierly" in my text editor and got a little red line underneath it. I must admit I was unsure about the spelling but was a bit surprised when I didn't find a spelling suggestion. I googled it and Google also suggested: "Did you mean: earlier?". Now I wonder, is "earlierly" a construction that should be avoided? Is it perhaps even a case of such a strong word as incorrect? And, if so, (I am sure you can understand what I am trying to say, but) how should I instead put what I am trying to say?
EDIT: I wanted to use it a bit like: "I have earlierly introduced this problem". A bit like: "I have eagerly / happily / sadly introduced you to this"
