although, however
雖 centers on concession: marking a contrast or unexpected result, similar to 'although' or 'however'.
雖 combines 虫 (insect/reptile) with 隹 (short-tailed bird), but the historical reason for this combination is uncertain. It may have originally been a phonetic loan for the abstract meaning 'although'.
The left side 虽 looks like a mouth 口 over an insect 虫, and the right side 隹 is a bird. Imagine a bird trying to eat an insect, but the insect is protected by a mouth-like barrier: although the bird tries, it cannot reach the insect.
For スイ, imagine a bird trying to eat an insect, but it's too swift: swift -> スイ, although the bird is fast, the insect escapes.
one cannot understand even a holy man's teachings without study; one cannot know the abilities of a great man without putting him to use; one cannot know the delicious taste of fine food without eating it
even though; despite; notwithstanding
there must be a clear distinction between the upper and lower classes; even new shoes must not be worn on the head
