I have a question about the usage of the noun "channel" in this scholarly article:
A European economic crisis could affect the U.S. economy through several channels....
The financial sector is the channel that is most likely to transmit harmful effects of a European crisis to the U.S. economy.
I checked this dictionary and I could not find a definition for "channel" that would fit the usage of "channel" in the article. Could the usage be technical jargon?
