How to say "bottom" in Japanese

• 底そこJLPT N3approx.Common
  nounThe lowest part of a container, vessel, or the sea; also the sole of a shoe. When 'bottom' means the lowest part of a physical thing, this is the word you want.
  靴くつの底そこがすり減へってしまった。↗

  The soles of my shoes are worn.
• 裏うらJLPT N4approx.Common
  nounThe reverse or hidden side of something; its 'bottom' sense is the underside of an object, not the lowest part inside a container — for that, 底 is the word.
  靴くつの裏うらにガムがこびりついちゃった。↗

  There's gum stuck to the bottom of my shoe.
• ボトムCommon
  nounThe loanword; in fashion it refers to lower garments. For the bottom of a box, glass, or the sea, 底 is the word you want rather than this.
• 麓ふもとJLPT N2approx.Common
  nounThe foot or base of a mountain or hill. Its 'bottom' sense belongs to this landscape use only; it is not the word for the bottom of a container or object.
  山やまの麓ふもとに日ひが昇のぼるが早はやいかただ一人ひとり山やまを登のぼり始はじめた。↗

  The sun had barely risen at the foot of the mountain when she set out alone up the slope.
• 尻しりJLPT N3approx.Common
  nounThe buttocks; a person's or animal's behind. When 'bottom' means the backside, this is the word; it does not mean the bottom of a thing.
  彼かれは女の子おんなのこの尻しりばかり追おいかけている。↗

  He's always chasing girls.

Use 底 for the lowest part of a container or the sea, 裏 for the underside of something, 麓 for the foot of a mountain, 尻 for a person's behind, and 「ボトム」 as the loanword in fashion.
