shout, roar, bellow, scold
吒 centers on forceful vocal expression: shouting, roaring, bellowing, or scolding someone loudly.
吒 combines 口 (mouth) with 乇, which likely contributes a phonetic element. The character is associated with loud vocal sounds.
The left side is a mouth 口, and the right side 乇 looks like a person with arms raised. Picture someone opening their mouth wide and throwing their arms up to shout or roar.
For タ, imagine a loud shout that sounds like 'TA!' bursting from the mouth. The sharp 'ta' sound cues the reading タ while matching the shouting meaning.
