أنا أفضل أن أقرأ في الشرفة عندما يكون الطقس جميلا.

In Arabic, the verb often already shows the subject. So أفضل by itself can mean I prefer.

Adding أنا is optional here. It can be used for:

• emphasis
• clarity
• a more natural sentence opening in some contexts

So both are possible:

• أنا أفضل أن أقرأ...
• أفضل أن أقرأ...

The first one sounds a bit more explicit: As for me, I prefer to read...

أن is often used before a present-tense verb to express something like to do in English.

So:

• أفضل = I prefer
• أن أقرأ = to read

Together:

• أفضل أن أقرأ = I prefer to read

This is a very common pattern in Arabic:

• أحب أن أتعلم = I like to learn
• أريد أن أذهب = I want to go
• أفضل أن أبقى = I prefer to stay

So if an English speaker is looking for the Arabic equivalent of an infinitive like to read, one very common way is أن + present tense verb.

Yes. Both are possible, but they are structured differently.

• أفضل أن أقرأ = I prefer to read
• أفضل القراءة = I prefer reading

The first uses أن + verb.
The second uses a verbal noun, called a masdar.

In many situations, both are natural. But أن أقرأ may feel more directly tied to the action itself, while القراءة presents it more as the activity of reading in general.

The verb comes from the root related to reading: قرأ.

Its basic past-tense form is:

• قرأ = he read

The present-tense form for I read is:

• أقرأ

That first أ is the normal present-tense marker for I in many verbs.
The hamza in the middle area of the word is part of the root itself.

So أقرأ is not random spelling; it reflects the structure of the verb.

Literally, في usually means in, and على usually means on.

But languages do not always divide space the same way English does. In Arabic, في الشرفة is a normal way to express being on the balcony or in the balcony area.

So even though English says on the balcony, Arabic commonly uses في here.

This is a good example of why prepositions should often be learned with the whole expression, not translated one word at a time.

عندما means when.

In this sentence:

• عندما يكون الطقس جميلا = when the weather is nice

By contrast, عند usually means something like:

• at
• by
• near
• sometimes with in certain expressions

So:

• عند الباب = by the door
• عندما = when

Even though they look related, عندما functions here as a time word meaning when.

Both are possible, but they are used a little differently.

• الطقس جميل = the weather is nice
• يكون الطقس جميلا = the weather is / becomes nice, or more naturally here, when the weather is nice

After عندما, Arabic often uses a verb to form a full time clause.
So عندما يكون الطقس جميلا is a very natural structure meaning when the weather is nice.

It is similar to saying:

• when the weather happens to be nice
• when the weather is nice

So يكون helps build the time clause smoothly.

This is because يكون belongs to the family of verbs like كان.

With these verbs:

• the subject stays nominative
• the predicate becomes accusative

In يكون الطقس جميلا:

• الطقس is the subject of يكون
• جميلا is the predicate, so it takes the accusative ending

That is why it appears as جميلا rather than جميل.

This is a very important grammar pattern:

• كان الجو باردا = the weather was cold
• أصبح الطفل سعيدا = the child became happy
• يكون الطقس جميلا = the weather is nice

Yes. الطقس literally has the definite article الـ, so word-for-word it is the weather.

In Arabic, it is very normal to talk about general things this way:

• الجو = the atmosphere / the weather
• الطقس = the weather

English also usually says the weather, so this matches quite well here.

Yes, often you can.

So you could say:

• عندما يكون الجو جميلا

This also means when the weather is nice.

A small nuance:

• الطقس is often a bit more specifically weather
• الجو can mean atmosphere, air, or weather, depending on context

In everyday usage, both can work in sentences like this.

The noun الطقس is grammatically masculine singular, so the adjective agrees with it.

That is why we say:

• الطقس جميل
• with يكون: الطقس جميلا

If the noun were feminine, the adjective would also be feminine:

• الحديقة جميلة = the garden is beautiful

So the adjective is masculine here because it matches الطقس.

Yes, to some extent.

The given sentence is very natural:

• أنا أفضل أن أقرأ في الشرفة عندما يكون الطقس جميلا.

You might also hear variations such as:

• أفضل أن أقرأ في الشرفة عندما يكون الطقس جميلا.
• عندما يكون الطقس جميلا، أفضل أن أقرأ في الشرفة.

The second version puts the time idea first:

• When the weather is nice, I prefer to read on the balcony.

Arabic word order is often more flexible than English, but not every rearrangement sounds equally natural. The original sentence is a good standard model.

A careful pronunciation would be approximately:

ʾanā ʾufaḍḍilu ʾan ʾaqraʾa fī ash-shurfati ʿindamā yakūnu aṭ-ṭaqsu jamīlan

A few useful pronunciation notes:

• الشرفة is pronounced ash-shurfa..., because ش is a sun letter, so the l of ال assimilates
• الطقس is pronounced aṭ-ṭaqs, because ط is also a sun letter
• أقرأ ends with a hamza sound: aqraʾ
• جميلا in careful reading ends with -an, though in pause you may hear jamīla

That whole part is:

• عندما يكون الطقس جميلا

It breaks down like this:

• عندما = when
• يكون = is / be
• الطقس = the weather
• جميلا = nice / beautiful

So literally it is something close to:

• when the weather is nice

This whole clause tells you when the preference applies.
