I heard they might nullify the new policy at work.

Really? That would be a huge relief for everyone.

Yeah, it seems like it just wasn't working out as planned.

I agree! It’s good to know they can nullify it if it’s not beneficial.

Root Explanation

Nullify → It is formed from "nullus" (meaning none or not) and the suffix "-fy" (meaning to make or to cause to be). The word "nullify" means to make something null or void, effectively causing it to have no value or effect.

Memory Tip

Think of making something 'not' ('nullus') valid or effective — that's what nullify means.
