noun

der Teich, -e

pond

Ein kleines, meist stehendes Gewässer, das oft von Menschen angelegt oder gepflegt wird und in dem Pflanzen und Tiere leben können.

The German word "Teich" is a noun that means "pond". It specifically refers to a small body of still water that is typically artificial, though it can also refer to natural ponds. The word's meaning revolves around a more contained and smaller water body as opposed to larger lakes or bodies of water.

Words with similar meanings include:

"Weiher" (another term for a pond, often artificial and typically larger than a "Teich")
"See" (lake, referring to a larger and usually natural body of water)
"Tümpel" (pool or puddle, usually very small and often temporary)

Difference:

"Teich" versus "Weiher": Both can be used interchangeably, but "Weiher" generally connotes a somewhat larger pond.
"Teich" versus "See": "See" refers to a lake, which is significantly larger than a pond.
"Teich" versus "Tümpel": "Tümpel" is a much smaller and more temporary body of water, such as a puddle, often seasonal and not necessarily a defined pond like a "Teich".
