Inuit words for snow
It seems that the structure of the Inuit language makes it fairly pointless to talk about the number of words for a thing.
But the Eskimoan language group uses an extraordinary system of multiple, recursively addable derivational suffixes for word formation called postbases. The list of snow-referring roots to stick them on isn’t that long: qani- for a snowflake, api- for snow considered as stuff lying on the ground and covering things up, a root meaning “slush”, a root meaning “blizzard”, a root meaning “drift”, and a few others — very roughly the same number of roots as in English. Nonetheless, the number of distinct words you can derive from them is not 50, or 150, or 1500, or a million, but simply unbounded. Only stamina sets a limit.
