Postposed agreeing attribute

Understanding the postposed agreeing attribute is essential for reading advanced Czech texts.

1. Morphological Agreement
The most critical rule is that the postposed attribute generally must decline to match the head noun's case, gender, and number. It frequently utilizes active or passive verbal adjectives, as well as regular adjectives with their own complements or objects (e.g., krabice plná starých fotek – a box full of old photos).

2. When is it used?

• Expanded attributes (rozvitý přívlastek): Highly productive when the adjective or verbal adjective has its own modifiers or objects. If placed before the noun, the modifiers must precede the adjective (e.g., dne 1. ledna uzavřená smlouva). Postposition allows the much easier [Adjective + Modifiers] order (e.g., smlouva [uzavřená dne 1. ledna] – the contract concluded on January 1st).
• Bare attributes (holý přívlastek): If the attribute has no modifiers of its own, postposition is used in specific categories: scientific taxonomy (medvěd hnědý – brown bear), historical titles (Karel IV. – Charles IV), institutional names (Univerzita Karlova – Charles University), poetry, literature, or fairy tales (lesy hluboké – deep forests), enumerations and lists (oděvy pánské, dámské a dětské – men's, women's, and children's clothing), sequencing and numbering (lekce první – lesson one, cvičení páté – exercise five, strana desátá – page ten), contrast or emphasis (červené víno je zdravější než víno bílé – red wine is healthier than white wine), or expressive phrasing (ty kluku hloupá! – you silly boy! – note that this intentionally breaks gender agreement for emotional effect).
• With indefinite pronouns: It naturally follows pronouns like něco or někdo (e.g., něco dobrého – something good). Note: In standard Czech syntax, constructions like něco dobrého in the nominative and accusative cases are classified as a non-agreeing attribute (přívlastek neshodný) because the pronoun is in the nominative/accusative while the adjective is in the genitive. It only functions as an agreeing attribute (přívlastek shodný) in oblique cases where the cases actually match (e.g., instrumental: s něčím dobrým).

3. Punctuation Rules
Punctuation depends entirely on whether the attribute is restrictive or non-restrictive. In spoken Czech, commas enclosing a non-restrictive attribute correspond to distinct pauses and a drop in intonation:

• Restrictive (těsný): Essential for identifying the noun. No commas are used (e.g., Vlak přijíždějící k nástupišti 2 má zpoždění. – The train arriving at platform 2 is delayed.).
• Non-restrictive (volný): Adds supplementary information. It is enclosed in commas (e.g., Sněmovna, zabývající se návrhem, zasedla... – The Chamber of Deputies, dealing with the proposal, convened...).

4. Register and Alternatives
Expanded participial phrases are almost never used in casual spoken Czech. In everyday speech, native speakers strongly prefer full relative clauses using který (e.g., smlouva, kterou jsme uzavřeli... – the contract that we concluded...).

Note: Do not confuse this with the non-agreeing attribute (přívlastek neshodný), which also follows the noun but remains in its own case, usually the genitive (e.g., návrh zákona – a draft of the law). Additionally, distinguish it from an apposition (přístavek), which is a postposed noun phrase rather than an adjective or participle (e.g., Karel IV., římský císař – Charles IV, Holy Roman Emperor).
