Compact Participial Descriptions

In formal, journalistic, and administrative Serbian prose, participial condensation is occasionally employed for informational brevity. However, normative grammars emphasize that Serbian stylistically prefers finite relative clauses or reflexive passive constructions; heavy participial phrases often feel like unnatural calques and should be used with caution.

1. Structural Conditions and Mechanism
In standard Serbian normative grammar, adnominal participial condensation of relative clauses is strictly restricted to transitive verbs using passive past verbal adjectives (трпни глаголски придев). Active past participles (радни глаголски придев) cannot form participial modifier clauses with dependents (*путници стигли јуче, *човек пао с коња are ungrammatical).

Condensation operates on relative clauses where the head noun corresponds to the patient/theme of the verb:

• Transformation to Passive Participle: When condensing an active transitive relative clause, the active predicate is converted into a трпни глаголски придев. The relative pronoun is removed, and the participle agrees directly with the head noun in gender, number, and case: одлуке које је одбор донео на седници → одлуке донете на седници; роман који смо прочитали → прочитани роман.
• Underlying Passive Clauses: Dropping који and the auxiliary verb (је / су) leaves the passive verbal adjective: документи који су потписани на седници → документи потписани на седници; одлуке које су донете на седници → одлуке донете на седници.
• No Oblique Condensation: Clauses where који serves as an oblique prepositional argument (e.g., књига о којој смо говорили) can never undergo participial condensation.
• Avoid Calqued Agents: Agent phrases such as од стране + генитив are considered bureaucratic barbarisms in standard Serbian and should be omitted.
• Ensure full adjectival agreement (case, number, and gender) between the participle and its head noun.

2. Constraints on Verbal Aspect and Forms

• Verbal Aspect: Perfective verbs (свршени вид, e.g., донет, усвојен, потписан) are standard for expressing completed, resultant states. However, imperfective verbs (несвршени вид) are also fully grammatical and common when denoting continuous, iterative, or prolonged processes with duration or temporal adjuncts (e.g., мост грађен пет година, план припреман месецима, питања постављана током расправе). Isolated imperfective participles without such modifiers (e.g., *кућа грађена у центру) remain stylistically unnatural and are usually expressed via finite or reflexive clauses (кућа која се гради у центру).
• No Active Participial Clauses: While isolated intransitive active past participles can function as lexicalized prenominal adjectives (e.g., опало лишће, пропали план), active participles cannot take postnominal dependents or head attributive participial phrases (*путници пристигли јутарњим возом is ungrammatical; use путници који су стигли јутарњим возом).
• Verbal Adverbs vs. Participles: Forms ending in -ући / -ећи (глаголски прилог садашњи) are invariant adverbs modifying the matrix clause's verb, not adnominal attributes modifying nouns.

3. Position and Punctuation

• Postnominal Placement (Natural): Condensed participial constructions naturally follow the head noun (e.g., Сви радови предати после рока биће одбијени).
• Prenominal Placement (Restricted): While a single participial adjective can stand before a noun (усвојени предлог), extended prenominal participial constructions containing dependents (such as *јуче на седници усвојени предлог) are unidiomatic calques and must be avoided.
• Restrictive vs. Non-restrictive Punctuation: Defining participial phrases carry no commas, whereas non-restrictive appositive phrases providing parenthetical detail are enclosed within commas (e.g., Овај закон, усвојен после дуге расправе, ступа на снагу у јануару).
