Short Predicate Adjectives

Short predicate adjectives represent a historical remnant in the Polish language. Unlike standard adjectives, which can modify a noun directly, many short forms are primarily restricted to the verb być (to be) and its imperative form bądź, though notable exceptions exist.

1. Morphology
The 'shortness' is strictly a masculine singular phenomenon in modern Polish, where the final vowel is dropped, often resulting in a consonant ending:

• gotowy → gotów (ready)
• pełny → pełen (full)
• pewny → pewien (sure)
• godny → godzien (worthy)
• zdrowy → zdrów (healthy)
• ciekawy → ciekaw (curious)

Feminine, neuter, and plural forms for these words (like pewna, warta, winni) are morphologically identical to standard long forms. Note that rad (glad) is a defective adjective that only exists in this paradigm; there is no long form rady in the nominative. Another crucial example is powinien (should/ought to), which is historically and morphologically a short adjective derived from winien. Today powinien is a modal with its own person-and-gender paradigm: powinienem, powinnaś, powinien, powinniśmy. It is not simply an adjective without person forms.

2. Usage and Register
Most short forms are formal or literary. You will encounter zdrów in fixed expressions like Bądź zdrów! (Be well). However, several are standard in modern speech:

• pewien: In the masculine singular, this is used interchangeably with pewny to mean 'sure' (e.g., Jestem pewien).
• pełen: Frequently used when followed by a genitive complement (e.g., pełen nadziei).
• wart: The standard way to say 'worth' (e.g., Ten samochód nie jest tego wart).
• ciekaw: Often used in the phrase Jestem ciekaw... (I am curious/I wonder...).
• gotów vs gotowy: The difference is primarily one of style and register. Gotów is slightly more literary or archaic, while gotowy is standard for both readiness to act (e.g., Jestem gotowy pomóc) and completed states (e.g., Obiad jest gotowy).

3. Syntactic Restrictions
Short forms exist in the nominative case and the morphologically identical masculine inanimate accusative case (e.g., Mam pewien problem, Przyniósł pełen dzban). Most cannot be used attributively (you cannot say *gotów człowiek). However, there are two major exceptions: pewien is used before nouns to mean 'a certain' (pewien pan), and pełen is often used as an attribute, both pre-posed (pełen kosz kwiatów) and post-posed (kosz pełen kwiatów). When pewien and pełen are used attributively in oblique cases, they decline using standard long endings (e.g., pewnego, pełnym).
