Questions & Answers about Сигнализация защищает дом.
What does the noun сигнализация mean in English?
Сигнализация typically means an alarm system or security system—a device installed to alert occupants of potential danger or intrusion.
Why are there no articles like "the" or "a" before сигнализация and дом in the sentence?
Russian does not use articles. The language relies on context rather than words like "the" or "a" to indicate definiteness, which is why neither сигнализация nor дом has an article in the sentence.
What is the grammatical structure of the sentence Сигнализация защищает дом.?
The sentence follows a subject-verb-object order. Сигнализация is the subject (in the nominative case), защищает is the verb in the third person singular present tense, and дом is the direct object (in the accusative case). Note that for many inanimate masculine nouns (like дом), the nominative and accusative forms are identical.
Why is the verb защищает conjugated in this particular form?
Защищает is the third person singular form of the verb защищать in the present tense. It is correctly conjugated to agree with the singular subject сигнализация, making it clear that the alarm system is performing the action of protecting.
What case is the noun дом in, and why does its form remain unchanged?
Дом is used as the direct object in the sentence, which means it is in the accusative case. Since дом is an inanimate masculine noun, its accusative form is identical to its nominative form, so no ending changes are necessary.
