Lesson 33: Conditional sentences — im and im... haya

Part 1: Why isolate conditionals as a separate topic

Conditional sentences are "if X, then Y". In English you intuitively distinguish three cases:

• Real: "If it rains tomorrow — we'll stay home" (it really may rain)
• Hypothetical present: "If I were a millionaire — I'd buy an island" (I'm not a millionaire)
• Counterfactual past: "If I had known yesterday — I would have said" (I didn't know)

The big news: Hebrew collapses the last two cases into one construction. The same im... haya describes both "if I were a millionaire now" and "if I had known yesterday". Context disambiguates the tenses; the form is one. This is a rare case where Hebrew is simpler than English.

Part 2: Type 1 — real conditions with im

Formula: im + (future or present) , (future)

im (אם) = "if". The particle itself doesn't change, no person on it.

In real conditions both verbs usually sit in the future tense (L21). In English "if it rains tomorrow — we will stay home" has present in the condition and future in the main clause; Hebrew uses future + future more readily.

Hebrew	Translit	English
אם ירד גשם, נישאר בבית	im yered geshem, nisha'er ba-bayit	If it rains, we'll stay home
אם תבוא מחר, נדבר	im tavo machar, nedaber	If you come tomorrow, we'll talk
אם היא תרצה, היא תתקשר	im hi tirtse, hi titkasher	If she wants, she'll call
אם נצא עכשיו, נגיע בזמן	im netse achshav, nagia ba-zman	If we leave now, we'll arrive on time
אם תלמדו, תצליחו	im tilmedu, tatslichu	If you study, you'll succeed

Remember: im never carries "would" — it's a form for possible situations, where the question is still open.

Variant with the present in the condition

If the condition is a current habit / general rule, you can put the present (participle) in the condition and future or present in the main clause: im ata rotse, anachnu yecholim lalechet ("if you want, we can go"), im yesh zman, nedaber ("if there's time, we'll talk").

Subtlety: if you're sure the event will happen, an Israeli will say כש- (ksheh-, "when"), not אם ("if"). "When you come, we'll talk" = kshe-tavo, nedaber. That's L35. There are also formal alternatives — be-mida she- and bi-tnai she- ("on condition that").

Part 3: Type 2 — hypothetical conditions with im... haya

This is the heart of the lesson. Here Hebrew gives the English speaker a generous gift.

Formula: im + haya (by person) + present participle , haya (by person) + present participle

That is, both parts of the sentence — both the condition and the main clause — are built the same way: "haya by person" + participle. This is the Hebrew equivalent of English "would have / would be doing".

Conjugation of haya by person (this is the past of the verb ה-י-ה "to be")

Person	Form	Translit
ani (I)	הייתי	hayiti
ata (you, m.)	היית	hayita
at (you, f.)	היית	hayit
hu (he)	היה	haya
hi (she)	הייתה	hayta
anachnu (we)	היינו	hayinu
atem (you m. pl.)	הייתם	hayitem
aten (you f. pl.)	הייתן	hayiten
hem/hen (they)	היו	hayu

Trap: hayita (you m.) and hayit (you f.) are spelled the same — היית. Distinguish by context / vowel points.

Present participle (L8)

The participle agrees in gender and number with the subject of its own clause, like the ordinary present tense.

Canonical examples

Hebrew	Translit	English
אם הייתי יודע, הייתי אומר	im hayiti yode'a, hayiti omer	If I had known, I would have said
אם הייתי יודעת, הייתי אומרת	im hayiti yoda'at, hayiti omeret	If I (f.) had known, I would have said
אם היית בא, היינו שמחים	im hayita ba, hayinu smechim	If you had come, we would have been glad
אם הוא היה כאן, הוא היה עוזר	im hu haya kan, hu haya ozer	If he were here, he would help
אם היא הייתה בריאה, היא הייתה עובדת	im hi hayta bri'a, hi hayta ovedet	If she were healthy, she would be working
אם היינו עשירים, היינו טסים לחו"ל	im hayinu ashirim, hayinu tasim le-chu"l	If we were rich, we would fly abroad
אם הייתם לומדים, הייתם מבינים	im hayitem lomdim, hayitem mevinim	If you (m.pl.) were studying, you would understand
אם הם היו רוצים, הם היו באים	im hem hayu rotsim, hayu ba'im	If they wanted, they would come

Main observation: the structure im + haya/hayiti/hayita... + participle = English "if X were / had been + verb-ing". The parallel is almost ideal. Use it as a crutch.

One template — two tenses in English

This is critical. Hebrew does not distinguish "if I were a millionaire now" from "if I had been a millionaire in 2010". What distinguishes them is context — a time marker: achshav ("now"), az ("then"), etmol ("yesterday"), lifnei chamesh shanim ("five years ago"). The same Hebrew phrase may translate two ways:

Hebrew	Translit	English
אם הייתי יודע אתמול, הייתי אומר	im hayiti yode'a etmol, hayiti omer	If I had known yesterday — I would have said
אם הייתי יודע עכשיו, הייתי אומר	im hayiti yode'a achshav, hayiti omer	If I knew now — I would say

Same construction, different time anchoring — set by the adverb.

Part 4: Why "haya + participle" means "would"

The construction haya + participle exists in its own right and means "would do / would be". This is an analytic form: haya gives the "shade of unreality" ("would"), participle — the action itself.

Hebrew	Translit	English
הייתי רוצה לבוא	hayiti rotse lavo	I would like to come
היינו אוהבים את זה	hayinu ohavim et ze	We would like this
הוא היה אומר...	hu haya omer...	He would say... / He used to say...

"haya + participle" is the universal irrealis mode of Hebrew. When you put it inside an im-condition, you get a full hypothetical sentence.

Side-by-side comparison

English	Type	Hebrew	Structure
If it rains, we'll stay home	real	im yered geshem, nisha'er ba-bayit	im + future, future
If it rained, we would stay home	hypothetical	im haya yored geshem, hayinu nish'arim ba-bayit	im + haya + part., haya + part.
If I know, I speak	general	im ani yode'a, ani omer	im + pres., pres.
If I knew, I would say	hypothetical	im hayiti yode'a, hayiti omer	im + haya + part., haya + part.
If I had known yesterday, I would have said	counterfactual past	im hayiti yode'a etmol, hayiti omer	(same form + etmol)

The English-speaker's win: in English "if I knew" and "if I had known yesterday" differ by tense — and Hebrew similarly distinguishes them mainly by the adverb. This makes type 2 incredibly easy: one form, one anchor word.

Part 5: Subtleties and traps

Trap 1: haya agrees with the subject of each clause

In im hayiti yode'a, hayinu matslichim — these are different subjects in the condition and the main clause ("if I had known, we would have succeeded"). Each haya conjugates by its own subject.

Trap 2: the participle agrees in gender and number

The participle in both clauses agrees with its subject, like the ordinary present (L8): ani hayiti yode'a / yoda'at, hu haya yode'a, hi hayta yoda'at, anachnu hayinu yod'im / yod'ot.

Trap 3: clause order — free

You can put the main clause first and the condition second: Hayiti omer im hayiti yode'a — "I would have said, if I had known".

Trap 4: negation

The negation goes before the verbal part, not before im:

Hebrew	Translit	English
אם לא ירד גשם, נצא	im lo yered geshem, netse	If it does not rain, we'll go out
אם הייתי יודע, לא הייתי אומר	im hayiti yode'a, lo hayiti omer	If I had known — I would not have said
אם לא הייתי עייף, הייתי בא	im lo hayiti ayef, hayiti ba	If I were not tired, I would have come

Trap 5: haya can stand on its own ("would be")

Without a participle — it's simply "would be". im haya li zman = "if I had time" — the inverted form of the possession yesh li (L10) in irrealis mode. Yesh → haya (by person).

Hebrew	Translit	English
אם הייתי עשיר...	im hayiti ashir...	If I were rich...
אם היה לי זמן, הייתי בא	im haya li zman, hayiti ba	If I had time, I would come
אם הייתה לה מכונית, היא הייתה נוסעת	im hayta la mechonit, hi hayta nosa'at	If she had a car, she would drive
