Isn’t that a funny phrase? We all know what it means….but I wanted to know why we use that phrase…..and by the way, I am a bit under the weather today…So without further ado….lets examine this phraseology…. and below is what I found.
This phrase possibly has nautical or seafaring origins. Commenting on the origins of this expression, a website called The Phrase Finder mentions that in the old days, when a sailor was feeling seasick, “he was sent down below to help his recovery, under the deck and away from the weather.”
