Advanced Supine Constructions | Romanian Grammar

The supine is the most under-appreciated non-finite form in Romanian, and the one English speakers most often replace with something clumsier. Built as de + the invariable past participle (de făcut, de citit, de spălat), it carves out a niche no other form covers: subjectless "to-be-X-ed" meanings. Apă bună de băut is "water good to drink / good for drinking"; casa e de vânzare is "the house is for sale"; mai am de citit is "I still have reading to do". Crucially, the supine is invariable — unlike the participle in absolute constructions, which agrees in gender and number, the supine never changes. This page maps the supine's specialized jobs and shows why it beats both the agreeing participle and the subject-requiring conjunctiv in exactly these slots.

💡

The supine's core meaning is "to be X-ed" with no expressed agent — the focus is on the action-as-task or the action-as-property, not on who does it. Wherever English says "to do" / "for doing" / "to be done" without naming a doer, Romanian reaches for de + supine. That subjectless, agent-blurred quality is exactly what neither the agreeing participle nor the conjunctiv delivers.

Form: de + invariable participle

The supine is morphologically identical to the past participle but frozen — it does not inflect for gender or number, and it is almost always preceded by de (occasionally la, pe, or another preposition in specific constructions).

Verb	Participle (agrees)	Supine (invariable)
a face	făcut / făcută / făcuți / făcute	de făcut
a citi	citit / citită / citiți / citite	de citit
a spăla	spălat / spălată / ...	de spălat

This invariability is the single most reliable way to tell the supine from the participle: if the form agrees with a noun, it's a participle (or a participial absolute); if it stays fixed after de, it's a supine.

Job 1: the evaluative supine — greu/ușor/imposibil de + supine

The supine completes adjectives of difficulty, possibility, and judgment — greu (hard), ușor (easy), imposibil (impossible), simplu (simple), interesant (interesting). The pattern is adjective + de + supine, and it answers "hard/easy to do".

Textul ăsta e greu de tradus.

This text is hard to translate. (evaluative supine — note: NOT 'greu să traduc')

Mâncarea era ușor de digerat.

The food was easy to digest.

E imposibil de explicat în două vorbe.

It's impossible to explain in a couple of words.

The supine here is subjectless and passive-flavored: greu de tradus means "hard to be translated", with no one named as the translator. This is precisely where the conjunctiv (greu să traduc — "hard for me to translate") would force a subject and shift the meaning toward a specific person's difficulty. The supine keeps it general.

Job 2: the to-do supine — a avea + de + supine

The construction a avea ("to have") + de + supine expresses a pending task — "I have X to do", a grammaticalized to-do list. It is enormously common in everyday speech and is one of the supine's most useful jobs.

Mai am de citit trei capitole până mâine.

I still have three chapters to read by tomorrow. (a avea + de + supine — pending task)

Avem multe de discutat.

We have a lot to discuss.

N-am nimic de pierdut.

I have nothing to lose.

Closely related is the existential e + ceva/nimic + de + supine ("there is something/nothing to be X-ed"):

E ceva de văzut la muzeul ăla, merită.

There's something worth seeing at that museum, it's worth it. (de văzut = 'to be seen / worth seeing')

Nu mai e nimic de făcut.

There's nothing more to be done.

Job 3: agent-defocusing — casa e de vânzare

The supine after the copula a fi ("to be") assigns a passive, agentless property to the subject: e de vânzare ("is for sale"), e de făcut ("is to be done / remains to be done"). The point is to defocus the agent entirely — nobody is named as the seller or doer; the property simply attaches to the thing.

Casa e de vânzare de șase luni.

The house has been for sale for six months. (de vânzare = 'to be sold', agent suppressed)

Mașina e de reparat, nu de aruncat.

The car is to be repaired, not to be thrown away.

Mai e mult de muncit până terminăm.

There's still a lot of work to be done before we finish. (de muncit — agentless task)

This is one of Romanian's neat passive alternatives: instead of a full a fi + participle passive or a se-passive, the supine packages "is to be X-ed" compactly. The full menu of passive-avoidance strategies is on se-passive vs a fi.

Job 4: purpose after verbs of motion — la cules, la scăldat

After verbs of motion (a merge, a se duce, a pleca), the supine introduced by la expresses purpose — "to go [in order] to do X". This is an old, idiomatic pattern, especially alive with activities like harvesting, fishing, swimming, and gathering.

Mergem la cules de ciuperci în weekend.

We're going mushroom-picking this weekend. (la + supine = purpose of motion)

Copiii s-au dus la scăldat în râu.

The kids went swimming in the river.

Femeile au plecat la cules de vie.

The women went off to harvest the vineyard. (la cules de vie — grape harvest)

Here la cules is roughly "to the picking" — the supine behaving as a goal-noun. The conjunctiv alternative (să culegem) is also possible, but the la + supine framing is the more idiomatic, set-phrase choice for these traditional activities.

Job 5: the supine as a noun

Some supines have crystallized into full nouns, taking the definite article and entering everyday vocabulary. Mersul ("the walking / the gait / the going"), scrisul ("(hand)writing"), cititul ("reading"), and înotul ("swimming") are supine-derived nouns. The most idiomatic of all is la cumpărături ("shopping"), where the supine-noun denotes the activity.

Mersul pe jos îmi limpezește mintea.

Walking clears my head. (mersul — supine-noun, the activity of walking)

Scrisul lui e imposibil de descifrat.

His handwriting is impossible to decipher. (scrisul as a noun + evaluative supine de descifrat)

Mâine mergem la cumpărături.

Tomorrow we're going shopping. (la cumpărături — fixed supine-noun activity phrase)

These supine-nouns overlap with the long-infinitive nominalizations covered on nominalization strategies; the supine-noun (mersul) tends to name the concrete activity, while the long infinitive (mergerea) is more abstract and formal.

Supine vs participle vs conjunctiv: why the supine wins

The supine occupies the slot where the other two candidates fail:

Form	Subject?	Agrees?	Best for
Supine (de făcut)	none (agentless)	no	"to be X-ed" / task / property
Participle (făcut/făcută)	modifies a noun	yes	adjectival result: "a finished job"
Conjunctiv (să fac)	requires a subject	n/a	"for [someone] to do" — agent named

For apă bună de băut ("water good to drink"), the participle băută would mean "drunk water" (a result, agreeing with apă), and the conjunctiv să beau would mean "water for me to drink" (forcing a drinker). Only the supine de băut gives the agentless "fit to be drunk" — the property of the water, no drinker named. That subjectless "to-be-X-ed" reading is the supine's irreplaceable contribution.

💡

Diagnostic test: if you can paraphrase the English with "to be ___ed" or "for ___ing" and no doer is named, use de + supine. Hard to read → "to be read" → greu de citit. Nothing to do → "to be done" → nimic de făcut. Water for drinking → apă de băut. The moment a specific doer enters, switch to the conjunctiv (să).

Common Mistakes

Confusing the supine with the agreeing participle (the supine never inflects):

❌ Textele sunt grele de traduse.

Incorrect — the supine is invariable; it stays de tradus even with a plural subject.

✅ Textele sunt greu de tradus.

The texts are hard to translate.

Substituting the conjunctiv where the meaning is agentless:

❌ Apa asta nu e bună să bei.

Off — the conjunctiv forces a 'you'. For the property of the water, use the supine: bună de băut.

✅ Apa asta nu e bună de băut.

This water isn't good to drink. (fit to be drunk — no drinker named)

Using the infinitive or a finite clause for the to-do construction:

❌ Mai am să citesc trei capitole.

Not idiomatic for a pending task — use a avea + de + supine: Mai am de citit trei capitole.

✅ Mai am de citit trei capitole.

I still have three chapters to read.

Dropping de before the supine:

❌ E greu tradus textul ăsta.

Incorrect — the evaluative supine requires de: E greu de tradus.

✅ E greu de tradus textul ăsta.

This text is hard to translate.

Key Takeaways

The supine is de + the invariable participle — its invariability is what distinguishes it from the agreeing participle.
Its core meaning is subjectless "to-be-X-ed" — no agent named, focus on the action as task or property.
Five jobs: evaluative (greu de făcut), to-do (mai am de citit), agent-defocusing copular (casa e de vânzare), purpose after motion (la cules, la scăldat), and supine-nouns (mersul, la cumpărături).
It wins over the participle (which agrees and reads as a result) and over the conjunctiv (which forces a subject) precisely in agentless "to-be-X-ed" contexts.
Test: if English paraphrases with "to be ed" / "for ing" and names no doer, use de
- supine.
