Well this was all in casual context anyways. The words in position "X" is implied. By saying "who's good at essays" it is actually implied that we are talking about "X = writing essays." You keep me on guard, y'know that?DrMetallica said:Yeah, "who's good at essays" doesn't work either because there isn't a second verb. There should be another verb where the X is in: "who's really good at X essays", for example, "who's really good at writing essays" would work. But in "who's really good at essays" the second verb is ommited leaving it up for the reader to decide.
There are a number of possibilities I can think of:
"who's really good at googling essays"
"who's really good at criticizing essays"
"who's really good at deleting essays"
and so on...
Anyways, I sent my edited essay off. Hope it helps.
