peace be upon u all
excellent topic my sister Dew Drops. keep up the good work!
i just wish to add further explanation concerning the difference between US & UK English. the difference is not only in pronunciation
(النطق)
but also in spelling, vocabulary & grammar as Dew Drops explained before.
(الكتابة، المفردات، و النحو)
in addtion present perfect in arabic is better translated into
المضارع التام
God bless u all
