אגב and דרך אגב: By the Way

A digression is a two-part move: you step off the topic, and then you step back onto it. Learners pick up the opener quickly — אגב is one of the first markers anyone teaches — and then leave the side-track lying open, because nobody taught them the return. This page covers both halves.

אגב is Aramaic, and it means "on the back of"

Hebrew Wiktionary points it אַגַּב, marks the pronunciation agav — so agáv, stressed on the second syllable — and files it under מילים שאולות מהשפה הארמית, words borrowed from Aramaic. The derivation it gives is transparent and worth keeping: אַ־גַּב, Aramaic a (= על) plus gav, "on the back of another thing". A remark introduced by אגב is riding on something else. Wiktionary even notes where the phrase got its legal life, in the Talmudic acquisition rule קניין אגב קרקע, where movable property is acquired on the back of a land transaction.

Neither אגב nor דרך אגב carries a register label in any source consulted for this guide. Treat them as neutral-to-slightly-bookish and entirely at home in speech — but note that "no label" is a report about the dictionaries, not a measurement of how often Israelis say them, and this page does not claim a frequency.

דרך אגב, and a folk etymology to enjoy but not repeat

דרך אגב — dérekh agáv — is the longer, slightly more deliberate version. Wiktionary derives it as a partial loan translation (תרגום שאילה חלקי) of the Aramaic אגב אורחא, in which אורחא is Aramaic for דרך, "way". Half the phrase was translated into Hebrew and half was left as it stood, which is exactly what a partial calque is.

The same entry then records a second derivation: that דרך אגב is the דרך of אל״ף־גימ״ל־בי״ת — a way of speaking in which you start on topic א, get reminded of ג, and only then come back to ב. It is a delightful story, and Wiktionary labels it in as many words: אטימולוגיה עממית, folk etymology. Enjoy it as a mnemonic; do not pass it on as the derivation.

The other אגב: not a marker at all

Before it was a discourse marker, אגב was an ordinary adverb meaning incidentally, in passing, while doing something else — and that use is alive. Here it does not announce a digression to your listener; it says that one action happened alongside another. Wiktionary's own illustrative sentence is of exactly this kind: נסעתי לירושלים לקנות דירה ואגב נכנסתי לבקר את הדודה.

אגב כך: current in writing, invisible in the dictionaries

אגב כך — agáv kakh, "in the course of that" — is the written cousin. It is worth a paragraph precisely because of the awkward shape of the evidence: Milog returns no entry for it at all (לא התקבלו פירושים), and Hebrew Wiktionary has none either, yet it turns up in 198 Hebrew Wikipedia articles (insource regex, three runs, identical each time, 21 August 2026) — 79 of them with the phrase standing bare and 116 with a conjunctive vav in front of it, which is how the example below runs. So it is current written Hebrew that the dictionaries have simply not lexicalised. That is the honest report: neither "it does not exist" nor "it is common", but current and lexicographically invisible.

What Israelis actually open with

In speech, אגב competes with a handful of shorter things that do the same job by seizing the floor rather than by labelling the move.

Closing the loop: בכל אופן and בכל מקרה

Here is the half that gets skipped. Having gone off on a tangent, you owe your listener a signal that you are coming back — otherwise the conversation stalls while everyone works out whether the topic changed for good. בכל אופן and בכל מקרה both do this: they mean anyway, in any case, and their pragmatic job is to close the parenthesis. בקיצור can do it too, with a summarising flavour; it has its own page.

Common Mistakes

1. Opening a digression and never closing it. The most common failure on this page has no wrong word in it at all. The fix is one word — בכל אופן, בכל מקרה, בקיצור — placed where you resume.

2. Repeating the א־ג־ב letter story as an etymology. Hebrew Wiktionary prints it and then labels it אטימולוגיה עממית in the same breath. The actual derivation is Aramaic אַ־גַּב, "on the back of".

3. Stressing it on the first syllable. It is agáv, not ágav. Hebrew is full of contrastive stress, and a marker mis-stressed at the start of a sentence is the first thing a listener hears.

4. Using אגב to introduce your main point. It labels the remark as secondary. Put your real point behind it and your listener will file it away as an aside and stop attending. If the remark matters, drop the marker.

5. Treating רגע as rude. English hang on can be an interruption; Hebrew רגע is routinely a request to keep the floor you already have, which is a different act. Interruption proper is on interrupting.

Key Takeaways

• אגב is Aramaic: אַ־גַּב, "on the back of another thing", and Hebrew Wiktionary files it among the Aramaic loans. Stress it agáv.
• דרך אגב is a partial loan translation of Aramaic אגב אורחא, where אורחא means דרך.
• The א־ג־ב letter derivation is labelled folk etymology by the very entry that records it.
• Neither word carries a register label in the sources consulted here, and no source consulted measures how often either is said.
• אגב כך has no dictionary entry anywhere consulted, yet appears in 198 Hebrew Wikipedia articles — current in writing, invisible to the lexicographers.
• אגב also survives as a plain adverb meaning in passing, with no discourse-marking job at all.
• A digression is two moves. בכל אופן and בכל מקרה are the second one.
