Formality and register
Pronouns, titles, and the moments when register shifts.
English has lost most of its formal-register distinctions. There is no "you" plural separate from singular, no T-V distinction, and titles have collapsed into Mr., Ms., Dr. and a few honorifics. Arabic has not lost these. Knowing when to switch register is a basic competence, and getting it wrong reads as either rude or strange.
The T-V distinction
Modern Standard Arabic does not formally distinguish between intimate and formal "you" the way French does between tu and vous. Instead, Arabic builds formality through honorific noun phrases used in place of the pronoun.
The plain second-person pronoun is anta (m.) / anti (f.) — أنتَ / أنتِ. In a formal setting this is replaced by something like HaDratak حضرتك ("your presence"), siyaadtak سيادتك ("your lordship," used for officials), or maʿaaliik معاليك ("your excellency," for ministers). The verb agreement shifts to third person to match.
In Egyptian Arabic, HaDritak is the everyday polite form — used to a stranger, a customer, an older person, an official. In the Levant HaDirtak is similar; siyaadtak is heavier and more deferential. In the Gulf, al-akh ("the brother") and al-ukht ("the sister") are common informal politeness markers.
Titles
Titles are used much more than in modern English. Skipping them in a context that calls for them is the equivalent of calling a stranger by their first name.
First names vs. titles
Title plus first name is the default for adults you do not know intimately: ustaadh Ahmad, duktoora Layla, Hajj Mahmoud. Title plus surname (Mr. Smith) is rarer in conversation. In professional contexts you may hear title plus full name.
First name alone is for friends, family, peers, and people younger than you. Using a first name with someone who expects a title is a marked choice — it can be intimate (welcome) or rude (unwelcome) depending on context. When in doubt, use the title.
One Egyptian habit: addressing a man with ya basha (يا باشا, originally "pasha") or ya bey, both Ottoman holdovers used now as friendly flattery rather than as actual rank. The Levant has its own informal honorifics — ya zalame ("hey man"), ya 3eyni ("my eye," affectionate).
The role of MSA in formal moments
Modern Standard Arabic is a register, not just a separate language. Speeches, sermons, news bulletins, official letters, and contracts are in MSA. Personal speech is in dialect. The line is not absolute: a speaker giving a public talk may begin in MSA and slide into dialect when the audience laughs, or use MSA phrases inside an otherwise colloquial sentence to mark seriousness.
For an English speaker, the most useful move is to recognize when MSA is being used and not to expect dialect features. A formal opening like ayyuhaa al-saada wa al-saadaat ("ladies and gentlemen") is not how you would address a friend.
How English speakers misjudge formality
Two common errors. First, defaulting to first names too early — Anglo professional culture treats first names as friendly, but in many Arabic-speaking workplaces this reads as a junior speaking out of turn. Second, over-correcting toward florid honorifics in casual settings, which reads as either sarcastic or foreign.
A safe baseline: title plus first name with anyone you do not know well, follow the lead of the person you are speaking with, and watch for when they relax into anta/anti as a signal that you can do the same.
