clean forgot

When I got back to the house, I felt for my handkerchief, and found that scalawag's roll o' bills, which I'd clean forgot.

I had a lot of other things to tend to and clean forgot it till you sent me Mr. Sowell's letter.

She's goin' round, doin' things inside there, but she's clean forgot how it's berry-day agin an' the crop wastin'.

I opened a drawer in the table and slipped it in, and I clean forgot all about it till a little while ago.

Has she clean forgot you, Dick, the little white mouse of a cousin, with the pretty blue eyes?
