(heel)
+ 日
(sun, day)
ONYOMI: SHI
SHE can't really put her heels over the sun, but the gist is she's tall!
DESCRIPTION: This is a COCK because the overwhelming majority of words which use 旨 mean "the gist of," but you'll never use those words! The only time you'll see it is in the context of 旨い(うまい)、which has nothing to do with gists!
KUNYOMI:
2: the main purpose or goal. Not so useful, but gives you a good idea of why this is called 'the gist.'
