Is there anything wrong in the following sentence :
I queried Sonia about her Personal Computer.
The sentence is akin to :
I asked Sonia about her Personal Computer.
Am I right ?
You are right. There's no difference in that sentence from "I asked Sonia...".
It just sounds a bit formal and stilted.
Edit: This is from Dictionary.com, the meaning of "query".
It's synonymous with "ask", and can be interchanged, as you like it. :)
