Long-form predicate: description, classification, characteristic
Long-form adjectives are the ordinary adjective forms used before nouns and also often as predicates:
- дом новый — the house is new
- книга интересная — the book is interesting
- вопрос сложный — the question is difficult
- студент внимательный — the student is attentive
- комната светлая — the room is bright
A long-form predicate can describe a quality, classify the subject, or present the subject as belonging to a category.
- Он больной человек. — He is a sick person.
- Он больной. — He is sick / he is a sick one; context may make it categorical, colloquial, or blunt.
- Это сложная задача. — This is a difficult task.
- Задача сложная. — The task is difficult.
Long forms are not “permanent” by default. Кофе горячий can describe a temporary state: the coffee is hot. Дверь открытая can describe the door as open. The issue is not simply time. The long form often presents the quality as a descriptive property of the subject.
Short-form predicate: current relevance, result state, evaluation, modality
Short forms often present a state as currently relevant, a result as achieved, an evaluation as concise, or an obligation/possibility as active.
- Кофе горяч. — The coffee is hot, but this sounds literary or marked; ordinary speech usually says кофе горячий.
- Документ готов. — The document is ready. Very normal.
- Дверь открыта. — The door is open / has been opened. This may also be a short passive participle, but for learners the result-state value is crucial.
- Ответ ясен. — The answer is clear. Formal/concise.
- Вопрос важен. — The issue is important/relevant. Common in formal or analytical style.
- Она права. — She is right. Normal.
- Мы должны уйти. — We must leave. Normal.
The short form is not always more temporary. Он прав does not mean he is right only briefly. Этот закон важен does not necessarily mean the law is temporarily important. The short form often marks the predicate as evaluative, situationally relevant, or constructionally fixed.
The больной / болен contrast
Consider the pair:
- Он больной.
- Он болен.
Он болен is a short-form adjective. It often appears in written, medical, formal, or serious contexts. It states a condition.
- Пациент болен. — The patient is ill.
- Он тяжело болен. — He is seriously ill.
- Ребёнок болен уже неделю. — The child has been ill for a week.
Он больной is a long-form predicate. It can be neutral in some everyday contexts, but it can also sound like classification: “he is a sick person.” Depending on intonation and context, it can be sympathetic, factual, dismissive, or stigmatizing.
- Он больной, ему нужен врач. — He is sick; he needs a doctor.
- Он больной человек. — He is a sick person.
- Не кричи, он больной. — Don’t shout; he is ill/sick.
A cautious production default is this: for formal or medical “is ill,” use болен / больна / больно / больны where appropriate. In everyday speech, listen closely to native patterns and be cautious because больной can classify a person in ways English “sick” may not.
Ready: готовый vs готов
This pair shows a stronger contrast:
- готовый проект — a ready/prepared project
- проект готов — the project is ready
- готовый ответ — a ready-made/prepared answer
- ответ готов — the answer is ready
Saying проект готовый is possible only with a special descriptive or contrastive meaning, for example “the project is a ready-made one,” not the ordinary “the project is ready.” The normal predicate for readiness is short: готов.
Right and correct: правильный vs прав
English “right” hides two Russian patterns:
- правильный ответ — correct answer
- ответ правильный — the answer is correct
- ты прав — you are right
- она права — she is right
- вы правы — you are right
Do not say ты правильный to mean “you are right.” That means something like “you are proper/correct” as a characteristic of the person, and it sounds wrong for agreement with an opinion. Use ты прав / ты права / вы правы.
Open, closed, occupied, free: adjective or participle pressure
Some predicate pairs overlap with short passive participles:
- дверь открытая — the door is open, descriptive
- дверь открыта — the door is open / has been opened, result state
- магазин закрытый — the shop is closed as a descriptive condition or type, but context matters
- магазин закрыт — the shop is closed, result/status
- место свободное — the seat/place is free, descriptive
- место свободно — the seat/place is available, often concise/official
- место занято — the seat/place is occupied
The short forms are common in signs and institutional language because they state status efficiently: закрыто, открыто, занято, свободно.
Degree and excess: short forms with too/insufficient meaning
Some short-form predicates imply that a quality is excessive, insufficient, or relevant to a standard:
- Комната большая. — The room is large.
- Комната велика для одного человека. — The room is too large / rather large for one person; formal or evaluative.
- Пальто маленькое. — The coat is small.
- Пальто мало. — The coat is too small / not enough in size, depending on context.
- Ответ простой. — The answer is simple.
- Ответ прост. — The answer is simple, often concise/formal; may carry evaluative force.
This is another reason “temporary vs permanent” fails. The short form may relate the quality to a standard, not to time.
Register differences
Some short forms are neutral and frequent:
- готов
- рад
- прав
- должен
- согласен
- уверен
Some are common but more written or formal:
- важен
- известен
- ясен
- сложен
- полезен
- опасен
Some long-form predicates are ordinary and neutral where the short form would be literary or stiff:
- Кофе горячий is ordinary.
- Кофе горяч sounds literary/marked.
- День тёплый is ordinary.
- День тёпел sounds literary.
Do not convert every long predicate into a short form. Short forms are powerful, but they are not universally natural.
Contrast sets
Illness
- Он больной. — He is sick / a sick person; context-sensitive, potentially categorical.
- Он болен. — He is ill; formal/current/medical tone.
Readiness
- готовый документ — a prepared document
- документ готов — the document is ready
Correctness
- правильный ответ — correct answer
- ответ правильный — the answer is correct
- ты прав — you are right
Importance
- важный вопрос — an important question
- вопрос важен — the question is important/relevant, often formal or focused
Availability/status
- свободная комната — a free/available room
- комната свободна — the room is available
- дверь открытая — the door is open as a descriptive condition
- дверь открыта — the door is open/opened as a status/result
Common learner misreadings
The first error is applying the temporary/permanent rule mechanically. Он прав is not merely temporary; кофе горячий may be temporary. The rule is only a rough hint, not a decision procedure.
The second error is using long forms for fixed short-predicate meanings: я готовый, ты правильный, она должная. These do not express the intended meanings “I am ready,” “you are right,” “she must.”
The third error is overusing short forms where they sound literary or unnatural. Кофе горяч may be grammatically possible, but кофе горячий is the safer neutral default.
The fourth error is missing register. Он болен and он больной can both refer to illness, but they differ in tone and possible implication.
The fifth error is forgetting agreement. A female speaker says я готова, я права, я должна, я уверена.
Build a “long vs short” comparison notebook. For each adjective, write three lines:
- Attributive long form: готовый документ.
- Long predicate, if natural: документ готовый — marked; means ready-made/prepared as a characteristic.
- Short predicate: документ готов — normal meaning: the document is ready.
Do this with high-value pairs:
- правильный ответ / ответ правильный / ты прав
- больной человек / он больной / он болен
- важный вопрос / вопрос важный / вопрос важен
- свободное место / место свободное / место свободно
For each pair, add a register note: neutral, formal, colloquial, marked, medical, official, or potentially rude.
Final rule
Do not reduce long-form vs short-form adjectives to temporary vs permanent. Choose by construction, lexical habit, register, and meaning: long forms often describe or classify; short forms often state predicate status, relevance, evaluation, or obligation.
