orders
詻 centers on authoritative commands: formal orders or instructions given with the expectation of being followed.
詻 combines 言 (speech) with 各, which likely contributes the sound. The character is associated with giving orders or commands through speech.
The left side 言 represents words or speech, and the right side 各 looks like a person standing firm. Picture someone issuing firm orders with their words.
For ガク, imagine a stern officer barking orders at a gak (invented sound like 'gawk') of startled recruits: gak -> ガク, and the words 言 on the left are the commands.
