dollar

JLPT0 G13 S0 F5000

The relevant seal inscription form shows a hanging vine or beanstalk + 八# split right and left → split/part twisting vines and stalks away to both sides → *negation* (← sweep away/dismiss; compare 不 and 非). *Dollar* is a borrowed meaning (via the similarity of 弗 and the dollar sign).
