"Arabic" on a booking form tells an interpreter almost nothing. The spoken varieties used across the Arab world differ enough that a speaker of one can struggle to follow another, and the gaps that matter most in a legal setting are precisely the ones a generic booking ignores. Identifying the dialect at first instruction is quick, and it prevents the mismatch that otherwise emerges live.
In short
- Ask where the client is from and how they speak at home — not which Arabic they read.
- Yemeni and Sudanese are the highest-risk for misassignment because UK pools are small.
- When unsure, let the interpreter help confirm dialect from a short sample before the hearing.
Why one word is not enough
Modern Standard Arabic (MSA) is the written, formal register — the Arabic of documents and broadcasts. Almost no one speaks it at home. Day-to-day speech is regional: Gulf, Levantine (Syrian), Iraqi, Sudanese, Yemeni and others. A client may read MSA fluently and still give their account in a regional dialect an MSA-only interpreter renders imperfectly. The detail lost is rarely the gist; it is the specific, case-deciding nuance.
How to identify it at first instruction
You do not need to be a linguist. Ask three things: which country the client is from, which region or city within it, and whether anyone has had difficulty understanding them before. Country of origin is the strongest single signal — a client from Sana'a needs Yemeni, not "Arabic". Where a client has lived in several countries, ask where they spent their formative years, because that usually shapes the spoken variety.
If the answer is uncertain or mixed, say so on the instruction. A good interpreter would rather confirm dialect from a short spoken sample in advance than discover a mismatch when the recording is running.
The high-risk dialects
Yemeni and Sudanese Arabic carry the most risk in UK proceedings, for the same reason: the qualified interpreter pool for each is small, so the temptation to substitute a more available variety is strong. That substitution is where accounts get flattened and apparent inconsistencies appear. For these two in particular, specify the dialect explicitly and confirm the interpreter actually works in it.
