Possession, duals and their cases

1)How come 'The lord of the two easts' in the arabic is written as possessor first and possessed afterwards?
If I were with my lack of knowledge to break that down I would have put mudaf ilayhi as the 'the two easts' but that cant be the possessor?
same with Ayat in Surah An-Naas 'the god of mankind'

2)When dual(ising)words... does the Harf 'ya' always signify the accusative case? and the the alif the nominative case? what about the genitive case? How do we know which case it should be?

3)If I were to change فهم to the present it is يفهم If i were to change it to the feminine present tense would it be يَفْهَمَتَ

4)In lesson 4 the homework 'two heavy words on the scale' the word scales was put as tanween ميز١نٌ How come it isnt majrur? Doesnt the preoposition before that affect the tanween?

1) In this sentence it still follows the 'possessed first and then the possessor'

Think of it like this بيت الولد
means 'the house of the boy' however in English we say 'the boy's house'. Similarly we say the two east's lord.

I don't like to say this but the term lord in this case is the possessed one because he is their lord.


2)genetive is also shown by 'Ya' the same as accusative.

3)تَفْهَمِيْنَ

4) I could not find this in the homework maybe you can post the the exact way it is written

I think I know which question is being reffered to here; Two heavy words on the scales. Yet على does not influence المزان if we were to apply the normal rules we would presume the correct way to say this is على المزين ....?

I was a bit stumped by this myself. The latter sounds incorrect...true?

Should you say;

على الميزانِ

then it would be majroor.

However, note you were asked to say "in" and so you should have used في. Nonetheless, the same concept still applies.

Ok was redoing my homework and this time understanding it just that little bit more. I thought ok I got the GRAMMATICAL break down of the dual case Marfu' indicated by bil alifi.. How come في. الميزانِ is majrur bil alifi and not by bil ya i?

المزانُ is actually not a dual but a single noun as it means 'scale' and not 'two scales.' Having said this, the word does imply the idea of two balances (I think).

Notice the default case, marfu' is indicated by ضمة so the word is not المزانِ but المزانُ or مزانٌ so the normal grammar rules apply.

The rule of duals will apply were we to say 'two scales' as in two different complete scales, in such a case the word does become a dual.
