‘aalam عالم = world
‘alam علم = standard
BTW, ‘alam refers to battle standards in general.
“Omrah” (actually “umaraa”) does not mean “nobleman”; it is the plural of “Ameer”, which does mean “nobleman” or “leader”.....
“divan” = poetic collection
“diwan” = prime minister
Neither Urdu nor Farsi has the “w” sound, so the two words are pronounced identically as “divan”. However, the word comes from Arabic, where it has the “w” sound....
