I am wondering about the below expressions. I came up with the second but the text book shows the first. Which one is more natural and the your reason for it. Please help! (Also correct my English if you find them to be not the way expressed by a native speaker). 1. In a bottom drawer. 2. In a bottom of the drawer. The first one because "of the" is understood in this sentence. However, you cannot use "bottom sea". You must use "bottom of the sea"! For example, "The ship sank to the bottom of the sea."

"In a bottom drawer" means that in a bureau or dresser or desk, where there are many drawers, you are talking about the lowest of the drawers. For example, "Go to my desk, and in the bottom drawer on the right side you will find the file you want." "In the bottom of a drawer" means that in any drawer in a bureau or desk, you a talking about the bottom of THAT drawer. For example, "Go to my desk, and in the bottom of the top drawer, under the other files, you will find my list of computer passwords." Your comment: "but my text shows me fist one" - should be, my text shows me the FIRST one." "Fist" is what you get when you curl up your fingers ready to punch someone like a boxer fighter does, and what you get is a FIST.

Yeah the first expression sounds more natural, like IanVincent said. If you'd go for the second expression, go for 'In the bottom of the drawer' instead.

The first expression sounds more natural, "in a bottom drawer". There is no need to say "of the" in the phrase, "in a bottom of the drawer".
