אז: So, Then, Well

אז az is two letters long and you will hear it in almost every Israeli conversation you are part of. It has four distinct jobs, and English does not slice them the same way — three of the four land on English so and the fourth on then. Getting all four is the cheapest upgrade available to an A2 speaker.

It is also old. Hebrew Wiktionary tags both of its senses רובד מקראי — the Biblical layer — and traces the word back beyond Hebrew, to Ugaritic. It gives it no register label at all, which is worth stating plainly: אז is not slang. What is informal is one of its uses, not the word.

One pronunciation note before anything else: אז is a single syllable, so it takes no stress mark. It is simply az — never áz. Once a prefix joins on it becomes two syllables and the stress shows: ואז ve'áz, מאז me'áz.

Job 1: "then" in the past

The oldest use. אז points at a time already established in the conversation and means "at that time".

Job 2: "so" before a consequence

Two clauses, and אז stands at the front of the second one: cause first, result after. This is the mirror image of English because, which puts the cause second — and switching between the two orders is where learners lose the thread.

Job 3: opening your turn

This is the job learners never acquire, because the word looks like it must be connecting something. אז at the very start of a turn joins nothing to anything. Structurally it is not a conjunction at all — there is no first clause for it to attach the second one to. What its position does is announce two things at once: I am taking my turn now, and what I am about to say follows on from what you just said.

An English speaker hearing that opening אז will look for the thing it refers back to and find nothing, and conclude they missed something. Nothing was missed. The word is doing the job that English does by starting a sentence with So, — and, like the English one, it is a feature of speech rather than of writing.

Job 4: אז מה?

אז מה? is a fixed two-word turn and it is dismissive: so what?, and? It rejects the relevance of what was just said rather than answering it. Its expanded form is אז מה אם — "so what if".

Careful here, because the same two words can open a genuine question. אז מה עושים? — "so what do we do?" — is a real request for a suggestion, and the verb after it is what makes it one. Bare אז מה?, with nothing following, is the dismissal.

ואז: the engine of a spoken story

ואז ve'áz, "and then", is how Israelis chain the events of a narrative. It is not elegant and it is not supposed to be — in speech it is the standard connector between one thing that happened and the next.

Now the same four events written up as a report. Nothing about the spoken version is wrong; it is simply built out of a different set of parts.

Two swaps do most of the work: ואז becomes לאחר מכן, and consequential אז becomes לכן. That is a register ladder, not a correction. A report built on ואז reads as a spoken account transcribed; a conversation built on לאחר מכן reads as a form being filled in. Both sets are correct Hebrew, and the choice is what you are writing.

מאז: frozen, and not the same word

מאז me'áz is מ + אז welded together into a single preposition meaning "since". It behaves nothing like the discourse marker: it takes a time expression, or a clause with ש, and it is at home in writing.

Common Mistakes

1. Using כל כך to join two clauses. English so covers both consequence and degree, and only one of them is אז. כל כך is the degree word — so hot, so tired — and it cannot connect two clauses.

2. Using אז as a degree word. The mirror error, and the one that follows from learning "אז = so" too well. אז never intensifies anything — put it in front of an adjective and it still means "at that time", so the sentence stays grammatical and quietly says something you did not mean.

3. Reaching for אז when the sentence wants a reason. Both of the sentences below are correct Hebrew and mean the same thing, and which one you need depends on which clause you say first. If the cause comes first, use אז. If the result comes first, you need כי — and אז will not do the job.

4. Hunting for what the opening אז refers to. When a turn starts with אז there is nothing before it in that turn, and nothing has been elided. Treat it as a signal about the conversation — a turn is starting, and it connects to yours — rather than as a word with content.

5. Hearing אז מה? as a question. Said flat and on its own it declines to engage. If a suggestion is genuinely being invited, something follows it — אז מה עושים?, אז מה אתה מציע? — and the extra words are the tell.

Key Takeaways

• אז is one syllable and takes no stress mark: az. With a prefix it becomes two — ve'áz, me'áz.
• Four jobs: "then" in a past narrative, "so" before a consequence, the turn-opener that English writes as a sentence-initial So,, and the dismissal אז מה?
• Consequential אז puts the cause first. כי and מכיוון ש put the cause second. Same meaning, opposite order.
• ואז is the ordinary spoken chain between events; the written-up version swaps it for לאחר מכן, and consequential אז for לכן. That is register, not correction.
• מאז is a separate, frozen preposition meaning "since", at home in writing.
• English so splits in Hebrew: consequence is אז, degree is כל כך, and neither can do the other's job.
• Hebrew Wiktionary tags אז רובד מקראי with no register label. The word is neutral; only its turn-opening use is specific to speech.
