contestar
to dispute or answer a claim
Use contestar for opposing an assertion or decision, including responding to a legal action.
How to choose
- impugnar: Choose impugnar if the sentence points to attacking the validity, admissibility, or correctness of an act, document, candidate, or evidence.
- contestar: Choose contestar if the sentence points to opposing an assertion or decision, including responding to a legal action.

The party challenged the candidacy.

Common trap
Not every disagreement is an impugnação. The formal remedy usually requires a defined object and procedure.
Practice it in context
Pick one sentence from your real life and write it twice: once with impugnar, then once with contestar. If both versions feel possible, name the meaning shift.
