She wore a disguise, so I wasn’t sure who she was.

To clarify: to explain or make something clear

We weren’t sure what he meant until he clarified his ideas.

Everyone was confused until she clarified what she meant.

To confuse: to make things difficult to understand; the opposite of to clarify.

Everyone was confused because her presentation was so disorganized.

He confuses people because he keeps changing his ideas.

  The instructions were confusing, so nobody knew what to do.

To ignore:  to try not to notice or deal with  something; to act as if something isn’t there.

We tried to ignore her, but she finally stood up and told everyone to shut up.

People don’t respect or like her, so they ignore in the office.

To confirm: to indicate that something is  correct or completed  as expected.

  We weren’t sure if he was going to accept  our offer  until he called and confirmed it.

We can’t start the project without written confirmation that we agree on the details.
