Afield can mean far away. An example of this sense of afield is, “His wife loves it when he is far afield, as do most of his friends. He is a bastard and his wife ‘plays’ (wink, wink) with his friends when he is far afield.”
Hmm, maybe I should give her a call. I’m a lonely guy.
The distance doesn’t have to be physical. Another sense of the word afield is roughly synonymous with off-target or off-topic. For example, you might say, “her propensity to ramble led our conversation far afield. I didn’t mind because she is equally imbecilic no matter what she talks about.”
Afield can also mean in the field or in the outdoors. Being a city person, who thinks that people weren’t meant to venture beyond the boundaries of the greater downtown areas of major cities, I’m having trouble with understanding and coming up with an example for this sense of the word.
One of the dictionaries I consulted suggested that this meaning is usually used in reference to hunting. I’m not a hunter, so that’s no help. I don’t even hunt dust bunnies because I think they have as much right to live as any other creature that someone else hasn’t killed for me to eat.
All I can come up with as an example is, “It would be glorious to be afield on a clear, crisp autumn day if only afield were in the city.”
