Impugn

Impugn

<iym-pewn>

question; challenge; dispute;

to verbally attack someone to prove dishonesty.

He will impugn your story because it is unbelievable.

Memory trick:
impugn reminds of "I'm pug"
imagine a pug dog barking at you

At work:
You can't impugn my skills because my projects are a success.
