To say that they are ok if you are ok
The most appropriate reply would be "Thank you."
Shucks are the husks of the corn ear. People sometimes say "aw, shucks!" when they're slightly embarrassed. The implication is that they use that word instead of saying some other word starting with S that would not be as polite!
aw shucks
jazakallah
"Que pasa" means "what's up?" or "what's going on?" You would reply however you would reply to either of those questions.
Well, it would actually be ¿Que tal? And it means how have you been. You could reply " bien" (good) or "mal" (not so good). You could reply 'y tu?' ( ee too?) to say 'and you?'
Both are terms, but for different aspects of a reply. You would decide what form and language to use "for the reply to Anne." If you were describing the contents of the reply, not the form, you would say that a word or phrase was "in the reply to Anne."
Say Thank You, That's What I Say.
You could say, "I'll try."
This can be unanswered by no one replying, or say if you asked someone question and they did not reply it would be unanswered because they have not replied to the question you asked them.
The correct reply to "Godspeed" is "Thank you." It's a polite way of wishing someone a safe and prosperous journey or endeavor. So, next time someone tells you "Godspeed," just say "Thank you" and be on your merry way.
