لولا الصالة الرياضية لما رفع صديقي الأثقال.

Here لولا means if not for, were it not for, or had it not been for.

So:

• لولا الصالة الرياضية = if it were not for the gym

This is a very common Arabic way to make a counterfactual statement: Arabic presents one thing as the reason the result happened.

Also, this is specifically the noun + لولا pattern. When لولا is followed by a noun, it usually has this meaning. It is not the other لولا that can be used before a verb to mean something like why don’t...

Because لولا here is not a preposition. It does not govern the genitive the way في or من would.

In traditional grammar, the noun after this لولا is treated as nominative. So if you fully vocalized it, it would be:

• لولا الصالةُ الرياضيةُ

That can feel strange to an English speaker, because English if not for the gym looks like a prepositional phrase. But Arabic grammar is doing something different.

Literally:

• الصالة = the hall
• الرياضية = the sports/athletic

Together, الصالة الرياضية means the sports hall, which is the normal MSA way to say the gym or the gymnasium in many contexts.

الرياضية has ال because it is an adjective describing الصالة, and Arabic adjectives agree with the noun they describe in:

• definiteness
• gender
• number
• case

So since الصالة is:

• feminine
• singular
• definite

the adjective must match:

• الرياضية

No. Here لما is not the same as لَمّا meaning when or not yet.

In this sentence, it is best understood as:

• لَ = the lām used in the result clause of this kind of conditional
• ما = negation

So:

• لما رفع صديقي الأثقال = my friend would not have lifted weights

In unvocalized Arabic, these forms look the same, but grammatically they are different.

So here it is not lammā; it is more like la-mā.

Because this sentence is not just saying he did not lift weights. It is expressing a counterfactual result: he would not have lifted weights if the gym had not existed / been there.

In this pattern, Arabic commonly uses:

• لولا ... لَما + past verb

So:

• لولا الصالة الرياضية لما رفع صديقي الأثقال

is a standard way to say:

• Had it not been for the gym, my friend would not have lifted weights

By contrast, لم يرفع is just ordinary past negation: he did not lift. It does not, by itself, give the same counterfactual would not have feeling.

Because Arabic often uses the past tense form in counterfactual conditional structures where English uses would have + past participle.

So even though رفع is morphologically past tense, in this structure it corresponds to English:

• would have lifted
• or, with the negation here, would not have lifted

This is very normal in Arabic. The surrounding particles, especially لولا and لما, create the counterfactual meaning.

Because verb–subject–object order is very common in Arabic.

So:

• رفع صديقي الأثقال
• literally: lifted my friend the weights
• natural English: my friend lifted the weights

This is a normal Arabic sentence pattern:

• رفع = verb
• صديقي = subject
• الأثقال = object

You could also find subject-first sentences in Arabic, but verb-first is extremely common and very natural here.

Yes. رفع الأثقال is a very common expression meaning:

• to lift weights
• weightlifting

Word by word:

• رفع = lifting / to lift
• الأثقال = the weights, heavy things

So the whole phrase works much like a set expression in English.

Good question. In this kind of sentence, Arabic often leaves that idea understood.

So لولا الصالة الرياضية is understood as something like:

• were it not for the gym
• if the gym were not there
• if the gym did not exist
• if it were not for the existence of the gym

In more explicit wording, Arabic could say something with وجود (existence/presence), but usually it is unnecessary because the shorter لولا + noun pattern is standard and clear.

Yes, it usually does.

The logic is:

• Had it not been for the gym, my friend would not have lifted weights

This strongly implies that in reality:

• the gym did exist / was available
• and my friend did lift weights

So the sentence does more than describe a hypothetical situation. It also suggests the real outcome: the gym was the factor that led to the weightlifting.

That captures the basic idea, but it loses an important nuance.

Because of the gym, my friend lifted weights gives a straightforward cause.

But لولا الصالة الرياضية لما رفع صديقي الأثقال is stronger and more specifically counterfactual:

• Had it not been for the gym, my friend would not have lifted weights

So the Arabic is not just saying the gym was a cause. It is saying the gym was the decisive factor without which the action would not have happened.
