Learn Farsi: اعتدال در سیاست همیشه مفید است.

اعتدال (e'tedâl) is built on the root ع-د-ل ('-d-l), which relates to justice, fairness, or balance. If you plug those root letters into the e-C1-t-e-C2-â-C3 pattern, you get e-'-t-e-d-â-l. This Form VIII pattern often indicates a reflexive or resultant state, so here it represents the state of bringing oneself into balance, which translates as moderation.

What other words share the root of اعتدال that might help me remember it?

You probably already know words like عادل (âdel - fair or just) and عدالت (edâlat - justice). Spotting the ع-د-ل root in اعتدال makes it much easier to remember that it is an abstract noun meaning moderation or balance.

Does the word سیاست only mean politics here?

سیاست (siyâsat) can mean politics, but it is also the standard word for policy. Depending on the broader context, this sentence could equally mean that moderation in policy is always useful.

How exactly do we pronounce the ع (ayn) in the middle of the Efte'âl pattern in اعتدال?

In the e-C1-t-e-C2-â-C3 pattern, the first root letter (C1) sits between an e and a t. Since C1 here is ع, which is pronounced as a glottal stop in Farsi, you pronounce the word as e'tedâl with a slight catch in the throat. In fast, casual speech, this glottal stop often softens, making it sound almost like etedâl.
