פיעל vs הפעיל for Causatives

Two of the seven binyanim make causatives, and there is no rule that tells you which one a particular root uses. That sounds like a failure of the system and it is not — binyan membership is a lexical fact, learned with the verb, and this page is about what you can still say once you accept that.

The demonstration

Four verbs of the plainest kind — making somebody feel something, making something cold. All four are ordinary, all four are causative in the flattest sense, and they split across the two binyanim with nothing separating the groups:

Pealim returns nothing at all for השמיח and nothing but the adjective קָרִיר for הקריר. Meanwhile העציב and הצחיק are ordinary hif'il entries. Two causatives one way, two the other, and no property of the roots predicts the split. And note what the fourth column is not saying: ע־צ־ב has a thriving pi'el — עיצב "design". The slot is occupied by an unrelated verb, not left empty.

One root, both binyanim

Where a root does support both, the two verbs are not variants — they have divided the territory, and the division is different every time.

ג־ד־ל is the tidiest case and still not a rule. One intransitive pa'al, two causatives, and they split by what you are enlarging: living things take גידל, and size, quantity or scale takes הגדיל. Milog draws the same line in its definitions: גידל is glossed make grow, cultivate and act as a parent to, while הגדיל is make bigger — in size, quantity, scope or force. Nothing about "causative" predicts that split; you have to know it.

ס־ד־ר has no pa'al at all, so neither verb can be "the causative of" anything. Here the split is one of register and scale: סידר is what you do to a drawer or a bureaucratic mess, while הסדיר is what a law or an agreement does — Milog glosses it קבע כללים, סדרים או הוראות, laying down rules.

שׁ־ל־ם is the one that should settle the argument. Pealim marks the pa'al לִשְׁלוֹם "to be complete" as archaic, and what both live verbs actually attach to is the adjective שָׁלֵם "whole". Both mean, abstractly, make whole — and pi'el took that to pay while hif'il took it to complete. Two binyanim, one root, one underlying idea, and two modern verbs you would never guess from one another.

The one generalisation that survives

Not a rule — a tendency, and worth having because it is about argument structure rather than meaning.

Hif'il characteristically adds a participant to a verb that already exists. נכנס → הכניס, יצא → הוציא, עלה → העלה, לבש → הלביש: in each pair the base verb has a subject and no object, and the hif'il inserts a causer above it, pushing the old subject down into a direct object. That mechanism is worked through on the causative sense of hif'il.

Pi'el more often supplies a verb where no partner exists at all. דיבר, ביקש, חיפש, טייל, ניסה — the pi'el verbs of a beginner's first months, and essentially none of them has a pa'al counterpart in everyday use. They are not causatives of anything; they are simply the verb.

So the tendency is directional: hif'il does something to an existing verb; pi'el is often the verb. Use it to interpret a pair you have met. Do not use it to build one.

Nor is the split frozen: both patterns are open, and which one a new agentive verb lands in is register-conditioned rather than free — Bolozky (2007) finds hif'il still the preferred causative pattern in literary Hebrew, while colloquial Hebrew has switched to pi'el. The sourced productivity picture for all seven binyanim — including why hif'il is not closed — lives on what each binyan means.

The causative you can always build is neither of them

Where a root has no causative partner in either binyan, Modern Hebrew does not leave you stuck: it reaches for a periphrastic causative — גָּרַם ל־ or הִכְרִיחַ את, each with an infinitive — which works on every verb in the language. Their government and the reason Israelis still take the binyan partner wherever one exists (קיררתי את היין, not גרמתי ליין להתקרר) belong to the causative sense of hif'il and the causative chain; the side-by-side checklist is pi'el or hif'il?.

Common Mistakes

1. Reaching for hif'il because English says "make someone X". This is the error the whole page exists for: hif'il sounds like the causative binyan, so it becomes the default, and for a large share of roots the slot is empty.

2. Treating גידל and הגדיל as interchangeable. Both are causatives of גדל, and swapping them produces a sentence that parses and means something absurd.

3. Assuming שילם and השלים are the same verb dressed differently. Both sentences below are correct Hebrew, and they have nothing to do with each other — which is exactly the lesson. Learners who have been told hif'il is "the stronger causative" produce the second when they mean the first.

Key Takeaways

• Both binyanim build causatives and nothing predicts which one a root uses. "Make happy" is the pi'el שימח and there is no השמיח; "make sad" is the hif'il *העציב. "Cool something" is the pi'el קירר and there is no *הקריר; "make someone laugh" is the hif'il הצחיק.
• Where a root supports both, they have divided the territory: גידל raises children, הגדיל makes things bigger; סידר tidies, הסדיר legislates (formal); שילם pays, השלים completes.
• שׁ־ל־ם is the proof: the pa'al is archaic, both verbs attach to the adjective שָׁלֵם "whole", and make whole became pay in pi'el and complete in hif'il.
• The surviving generalisation is a tendency about argument structure: hif'il typically adds a participant to an existing verb (נכנס→הכניס, יצא→הוציא, עלה→העלה, לבש→הלביש); pi'el typically is the verb (דיבר, ביקש, חיפש, טייל, ניסה), with no pa'al partner to be causative of.
• Read the tendency backwards, to interpret a pair you have met — never forwards, to build one.
• Which binyan a new causative lands in is register-conditioned, not free: hif'il keeps the literary causative, pi'el has taken the colloquial one (Bolozky 2007). The sourced productivity picture is on what each binyan means.
• Where neither binyan has a causative, the periphrastic one always works — גרם ל־ or הכריח את, with an infinitive — and it is set out on the causative sense of hif'il.
• Pi'el is not the intensive binyan — its real niche is the factitive and causative one described here.
