הבין hevín, “understand, realize,” is a hollow hif'il verb from ב־י־ן. Its middle radical is י, even though hif'il makes it look exactly like the ע״ו verbs הכין (כ־ו־ן) and הביא (ב־ו־א). Learn that trio together for its shared shape, but do not reconstruct the root from the hif'il form: in this binyan, ע״י and ע״ו have merged.

The table gives ordinary Israeli pronunciation for second-person plural הבנתם / הבנתן, with he- and stem stress. The careful normative forms are הֲבַנְתֶּם / הֲבַנְתֶּן, havantém / havantén, heard in formal recitation. Modern תבינו / יבינו / הבינו serves plural groups of every gender.
לא הבנתי כלום; אפשר להסביר שוב?
lo hevánti klum; efshár lehasbír shuv?
I didn't understand anything; could you explain it again?
אתה מבין אותי, או שאני מדברת מהר מדי?
atá mevín otí, o she'aní medabéret mahér midái?
Do you understand me, or am I speaking too fast? (f. speaker, to a man)
The practical trap: הבין beside הבנתי
The long i and its yod disappear before consonantal past-tense suffixes. Set הֵבִין hevín beside הֵבַנְתִּי hevánti: the dictionary form and the form learners meet in conversation share only הב־ on the unpointed page. The same contraction gives הבנת, הבנו, הבנתם. It is systematic across hollow hif'il—compare הכין / הכנתי and הקים / הקמתי—but that regularity does not make an isolated הבנתי easy to look up.
The first-person plural deserves its own glance. Root-final נ meets the suffix ־נו and contracts to one written nun with a dagesh: הֵבַנּוּ, unpointed הבנו, not a visibly doubled spelling. Do not confuse it with הבינו “they understood,” whose yod remains.
רק כשקראתי את ההודעה שוב הבנתי מה קרה.
rak kshekaráti et hahoda'á shuv hevánti ma kará.
Only when I reread the message did I understand what had happened.
הבנו זה את זה בלי הרבה מילים.
hevánu ze et ze bli harbé milím.
We understood each other without many words.
Understanding a thing or a clause
A noun or pronoun is a direct object. A definite noun takes את: הבנתי את השאלה. An indefinite language name or subject can stand without it: היא מבינה עברית. A complete proposition follows with ש־, and embedded questions follow with למה, איך, מה, מתי without extra marking.
לא הבנתי את השאלה האחרונה במבחן.
lo hevánti et hashe'elá ha'akharoná bamivkhán.
I didn't understand the last question on the exam.
הבנתי שאיחרתי ברגע שראיתי את החדר הריק.
hevánti she'ekhárti baréga shera'íti et hakhéder hareík.
I realized I was late the moment I saw the empty room.
אני לא מבינה למה המחיר השתנה פתאום.
aní lo meviná láma hamekhír hishtaná pit'óm.
I don't understand why the price suddenly changed. (f. speaker)
The idiom מבין עניין means someone is capable and knows what matters; מבין דבר is a knowledgeable person or connoisseur, slightly more elevated. These use a bare noun, not את.
דבר איתה; היא מבינה עניין ותמצא פתרון מהר.
dabér itá; hi meviná inyán vetimtsá pitrón mahér.
Talk to her; she knows what she's doing and will find a solution quickly. (informal, to a man)
Expertise with ב־ and inference with מ־
With ב־, the verb means “know one's way around, be knowledgeable about” a field: מבין במחשבים, מבינה ביין. English normally says someone understands computers directly; the Hebrew preposition presents the topic as a domain of expertise.
אחי מבין במחשבים, אז ביקשתי ממנו לבדוק את התקלה.
akhí mevín bemakhshevím, az bikáshti miménu livdók et hatakalá.
My brother knows about computers, so I asked him to check the fault.
With מ־, a source licenses an inference: “from X, I understood that…” The conclusion itself usually comes in a ש־ clause.
מהשתיקה שלו הבנתי שהוא לא מסכים.
mehashtiká sheló hevánti shehú lo maskím.
From his silence I gathered that he didn't agree.
מזה הבנתי שלא כדאי לחכות יותר.
mizé hevánti sheló kedái lekhakót yotér.
From that I understood that it wasn't worth waiting any longer.
The noun family and fixed combinations
הבנה means understanding or comprehension: הבנה הדדית is mutual understanding, and הבנת הנקרא is reading comprehension. Huf'al adjective מובן means “understood, clear”; מובן מאליו is “self-evident, taken for granted.” When there is no understanding at all, colloquial Hebrew often chooses אין לי מושג, “I have no idea,” rather than a negative form of הבין.
אחרי השיחה הגענו להבנה הדדית.
akharéi hasikhá higánu lahavaná hadadít.
After the conversation we reached a mutual understanding.
תבין, זה לא פשוט לשנות הכול ביום אחד.
tavín, ze lo pashút leshanót hakól beyóm ekhád.
You have to understand, it isn't simple to change everything in one day. (informal, to a man)
אין לי מושג איפה שמתי את המפתח.
ein li muság éifo sámti et hamaftéakh.
I have no idea where I put the key. (informal)
Key Takeaways
- הבין is hollow hif'il, root ב־י־ן; hif'il makes it look like ע״ו הכין and הביא.
- The yod disappears in the suffixed past: הבין but הבנתי, הבנו.
- הבנו is “we understood”; הבינו is “they understood.”
- Use a direct object for content, ש־ for a proposition, ב־ for expertise, and מ־ for the evidence behind an inference.
- הבנה, מובן מאליו, הבנת הנקרא, מבין עניין are high-frequency members of the same lexical family.

- Hif'il Hollow Roots (ע״ו / ע״י): הבין, הכין, הביא, הקיםB1 — ע״ו and ע״י are two different classes everywhere except here: in hif'il both collapse onto one template, הֵ־ִי־, so הֵבִין (ב־י־ן), הֵכִין (כ־ו־ן) and הֵקִים (ק־ו־ם) are indistinguishable. The forms are uniform; the spelling of the past is where learners come unstuck.
- הכין — to prepareA2 — Conjugate the hollow hif'il verb הכין, handle its yodless past, and distinguish preparing something from getting oneself ready.
- הביא — to bringA2 — Conjugate the doubly weak verb הביא and use its concrete, result, consideration and expression frames naturally.
- ע״ו and ע״י (Hollow Roots) Across the BinyanimB2 — A root whose middle letter is ו or י usually has no middle consonant to build on, so each binyan solves the problem differently: pa'al shows two letters, hif'il inserts a long i, and the pi'el slot is often taken over by the polel. Pa'al keeps ע״ו and ע״י apart most transparently; an ordinary pi'el such as כיוון or קיים can reveal the root letter too.
