11d limp over tee
DOT
limp is the defn
O T = Over Tee (i think?)
D is missing from the wordplay and is part of the word to be shaded in that top corner
thanks very much Roslyn - I was looking for a word for tee that read backwards would be a synonym for limp! Done all the rest but still puzzled over the nine letter word that is suggested by 99a.
