ex:Ali fihim ad-dars=Ali understood the lesson(to make a passive we need to add ,"it" or "in" before the verb
Then conjugate verb into present so "fihim" in present (he understands) howe yifham (now the second vowel is quite important to create a verb in
passive )The second vowel is "a" so the passive verb will be
itfahamor infaham both means the same in EA
The sentence(always starting with object then passive verb
Ad-dars itfaham\infaham=The lesson was understood
ex no 2.
Fariid fahhim ali ad-dars=Ali explained the lesson to Ali
Conjugation in present tense "yafahhim"
ad-dars itfahhim le-Ali=The lesson was explained to Ali
Hope it is somehow clear
