oppose
咈 centers on vocal opposition: speaking out against something or refusing to agree. Its core idea is to oppose or contradict verbally.
咈 combines 口 (mouth) with 弗, which likely contributes a sound element. The character expresses opposition through speech.
A mouth 口 beside 弗, which looks like a bow being drawn back. Imagine someone pulling back a bow and shouting 'No!' in opposition.
For フツ, picture a person opposing a plan by blowing a fuse: fuse -> フツ, and their angry mouth 口 shouts opposition.
