What is the Kanji for すがり in 通りすがり?


I can't find any kanji or meaning for sugari or sugaru that matches that makes
sense for the meaning of 通りすがり.




It is 「縋{すが}る」 in kanji, but you would want to know that this kanji is
**_not_** taught in Japanese schools, so almost everyone would write it in
kana. I myself did not even know it until today.

「縋 **り** 」 is the continuative form of 「縋 **る** 」 that is used as a noun
(instead of a verb). 「縋る」 means **_"to rely on", "to cling to", "to hold on
to"_** , etc.

Thus, 「通りすがり」 would literally mean " ** _relying on a person in passing_** "
usually for obtaining some kind of information.
