Russian Forms/Inflections:
The primary translation "ядро" is a neuter noun in Russian, belonging to the third declension. It follows regular patterns for most cases but has some irregularities in plural forms. Below is a declension table for "ядро" in singular and plural:
Case | Singular | Plural |
---|---|---|
Nominative | ядро | я́дра |
Genitive | я́дра | я́дер |
Dative | я́дру | я́драм |
Accusative | ядро | я́дра |
Instrumental | я́дром | я́драми |
Prepositional | я́дре | я́драх |
For "ядро клетки", it remains invariable as a phrase, but "клетки" (genitive of клетка) follows standard feminine noun declension.
Russian Synonyms/Antonyms:
- Synonyms:
- ядрышко (diminutive form, used for smaller or less significant nuclei, e.g., in biology)
- центр (more general, meaning center, often interchangeable in metaphorical contexts)
- Antonyms:
- оболочка (shell or outer layer, contrasting with the core)
- периферия (periphery, for the outer parts)
Related Phrases:

- в ядре семьи - Translates to "at the heart of the family"; a metaphorical phrase for family dynamics.
Usage Notes:
The English word "nucleus" most directly corresponds to "ядро" in Russian, especially in scientific fields, but always consider the context to choose the precise translation. For biological contexts, "ядро клетки" is preferred for clarity. In formal writing, use the nominative form as a subject, but inflect it according to Russian case requirements (e.g., genitive for possession). English learners should note that Russian nouns like "ядро" have gender and require agreement in adjectives and verbs. When multiple translations exist, opt for "ядро" in physics and "ядро клетки" in biology to avoid ambiguity.
Common Errors:
- Using "ядро" without context: English learners often forget to specify, e.g., saying "ядро" for a cell when "ядро клетки" is needed. Correct: Use the full phrase in biological contexts to avoid confusion.
- Confusing inflections: Mistaking "ядро" in genitive as "ядра" when it should be "я́дра" for plural nominative. Error example: "Я имею ядра" (incorrect for singular possession); Correct: "Я имею я́дро". This happens because English doesn't have cases, so remember to check the sentence structure.
- Over-literal translation: Translating "nucleus of a group" directly as "ядро группы" is fine, but learners might misuse it in informal speech where "центр" is more natural.
Cultural Notes:
In Russian culture and education, terms like "ядро" are heavily emphasized in STEM fields due to Russia's strong history in space exploration and nuclear physics (e.g., contributions from scientists like Igor Kurchatov). This word often carries connotations of foundational importance, reflecting Russia's emphasis on scientific achievement in national identity.
