I know that to express gratitude or to thank are verbs that basically mean to say thank you, but what is the verb for the reciprocol action (i.e. saying you're welcome)?
Is there a word for this, and does it vary based on the response?
Like if I say thank you and you say go to H-E-double hockey sticks!. What did you do other than reply?
"Thank you" = to thank
"You're welcome" = to ???
