1.
bottomless; limitless; endless; insatiable
Describes something that seems to have no bottom or limit. Used both literally (a very deep place) and figuratively (an appetite, energy, or capacity that seems unlimited). Often carries a sense of awe or exasperation.

底なしの食欲で、いくらでも食べられる。
With a bottomless appetite, he can eat as much as you put in front of him.
この沼は底なしだと言われていて、近づくのは危険だ。
This swamp is said to be bottomless, so it's dangerous to go near it.
Composed of 底 (bottom) + なし (without). Functions as a の-adjective modifying nouns: 底なしの～. Can also be written 底無し.
COMMON COLLOCATIONS:
- 底なしの沼: bottomless swamp
- 底なしの体力: limitless stamina
- 底なしの食欲: insatiable appetite

USAGE:
The expression 底なし沼 is also used figuratively to mean something one gets deeply absorbed in and cannot escape from, similar to English 'rabbit hole.' For example, a hobby that becomes all-consuming: このゲームは底なし沼だ (This game is a bottomless pit).
