抗 oppose

I oppose COCAINE.

Put your hand up to oppose him laying his beret on top of your dirty cast-off diaper.

to counter ★★★☆☆
対 (against) + 抗 (oppose) = 対抗 (to counter )

to counter (used with two roughly equal things that oppose each other) (i.e. a counter-reaction, counter-demonstration, compete in the marketplace, counter-culture, antagonist, counter-balance)

resist ★★★☆☆
抵 (resist) + 抗 (oppose) = 抵抗 (resist)

to resist, used about one person taking on the whole fuckin' system, mannn!: draft resister, resisting arrest, La Resistance.

Also, to encounter resistance, resist temptation, and the electric concept of 'resistance' are also included in the meaning.

rebel ★★☆☆☆
反 (anti) + 抗 (oppose) = 反抗 (rebel)

to be rebellious, defiant. To start a revolt. Unlike the related words 抵抗　（ていこう）　and 対抗　（たいこう）、　反抗 has the nuance of 'rebel for the fuck of it,' like a teenager would.
