I'm looking for a word that I can't seem to find, and I'm struggling with how to find it. I'll use a blank in the place of the word and compare it other grammar to demonstrate what I actually mean:
Take predators and prey for instance:
The predator preys on the target; The prey is predated by the predator.
Comparing this to the word I'm looking for:
The [blank] targets the target; The target is targeted by the [blank]
I'm looking for a general word for something that does the targeting. Maybe I'm searching for a word that doesn't exist for a reason?
In response to suggestions of 'targeted': it's for a paper, so I wouldn't use a word that isn't in the dictionary. The exact context that I'm trying to use this word in is (in response to 'aimer'):
"There was a strong correlation between the length of the gene and the number of miRNAs that targeted it."
"There was a strong correlation between the length of the gene and the number of targeters it has". This works, but as it doesn't technically exist, and also sounds horrible, it won't suffice.
