Question 1

What does 'Salaam' mean in Arabic?

Thanks

 Question 2

Alaikum assalaam. I am trying to find out the actual translation of the reply greeting  

Wa alaikum assalaam wa rahmatu Allahi wa barakatuh. thank you.

 Answer

Wa alaikum assalaam, meaning “and to you peace”.  The literal translation would be “the peace”.

Salaam means peace.

The reply greeting:

Wa alaikum assalaam wa rahmatu Allahi wa barakaatuh, means: And to you [plural] is the salaam [peace] and Allah’s mercy and His blessings. 

You are both welcome.
