Say, I am applying for a job and the recruiter might call me at anytime and so I have to carry my phone with me all the time and to "ready to receive" the call from the recruiter.
I say "I have to listen for the call"
"Listen" relates to ears and now there are some similar actions but I don't use my ears but my eyes.
Say, it is a rainy season and my clothes are hanging out outside. It might rain at anytime and so I have to look out of the window to check if it is raining and to "ready to bring" the washing in.
Can I say "I have to watch for the rain"?
Is "to watch for something" the counterpart of "to listen for something"?
