Undecided questions
Arabic: What is the difference between "ما" and "ماذا" in Arabic? Please explain with examples.

We can say they have the same meaning.
We use them to ask about everything like (animals, things, stuff, acts..etc) except the people.
ما الأمر؟ = what's happen?
ماذا تفعل؟ = what are you doing?

use varies depending to the sentence.
but I think often (ماذا) is used for queries, and (ما) used to question.

hello there . both of them they are used in different contexts and sometimes can be used interchangeably . the following are some examples :
ماذا تفعل غدا؟what will you do tomorrow ?
ما سبب زيارتك ؟what is the reason for you visit ?
ماذا قال لك الاستاذ ؟what did the teacher tell you ?
ما هو لونك المفضل ؟؟what is your favorite color ?
؟ماذا تحمل بيدك ؟what are you holding ?
بماذا تحلم بما تحلم ؟؟what are you dreaming of ? or what do you dream of ? see that here both can be used .
with more practice , you will see the difference and will use them perfectly
I hope it would help .

ما there is many uses for it within the meaning of the sentence..we can use it as a question : what is ur point of view..ma houa ra'iok..actually we always use it after the third person singular pronoun (houa hia ) etc...also we use as a tool denied ex: wallahi ma fa'altoo shai'an = i swear i didn't do anything
ماذا we use it only for a question but we cant use it before the third person singular pronoun i mean for ex we can't say : matha houa yaf'al= what he is doing..we say matha yaf'al= what he is doing

ما is the same in ماذا
ما : what
ذا : harfou ichara
expl: ما الذي
ماذا
ما هذا
ما هو
ذا، هذا، الذي : للإشارة to show !
