porosity
Russian Translation(s) & Details for 'porosity'
English Word: porosity
Key Russian Translations:
- пористость [pɐˈrʲistəstʲ] - [Formal, Scientific]
Frequency: Medium (This term is commonly used in technical, scientific, and geological contexts but less so in everyday conversation.)
Difficulty: B2 (Intermediate; requires familiarity with scientific vocabulary and basic Russian noun declensions, as per CEFR standards.)
Pronunciation (Russian):
пористость: [pɐˈrʲistəstʲ]
Note on пористость: The stress falls on the third syllable ("sto"), which is common in Russian abstract nouns. Be mindful of the soft 'r' sound, which can be challenging for English speakers.

Russian Forms/Inflections:
"Пористость" is a feminine noun (third declension) derived from the adjective "пористый" (porous). It follows regular patterns for abstract nouns ending in -ость, which means it inflects based on case, number, and gender. As a singular noun, it does not have a plural form in most contexts but can be used in plural for specific types (e.g., in scientific comparisons).
Case | Singular | Plural (if applicable) |
---|---|---|
Nominative | пористость | пористости (e.g., for multiple types) |
Genitive | пористости | пористостей |
Dative | пористости | пористостям |
Accusative | пористость | пористости |
Instrumental | пористостью | пористостями |
Prepositional | пористости | пористостях |
Note: This is a regular inflection pattern; no irregularities to note.
Russian Synonyms/Antonyms:
- Synonyms:
- проницаемость (permeability; similar but focuses more on the ability to pass through, often used interchangeably in some contexts but with a subtle difference in material science)
- пустотность (voidness; less common, emphasizes empty spaces)
- Antonyms:
- непористость (non-porosity; directly opposite, indicating a lack of pores)
- плотность (density; antonym in the sense of compactness, though not exact)
Related Phrases:
- коэффициент пористости - Coefficient of porosity; used in engineering to quantify pore volume in materials.
- эффективная пористость - Effective porosity; refers to the interconnected pores that allow fluid flow, common in geological studies.
- общая пористость - Total porosity; encompasses all void spaces, regardless of connectivity.
Usage Notes:
In Russian, "пористость" directly corresponds to the English "porosity" in scientific and technical fields, but it is primarily used in formal contexts like research papers or lectures. English speakers should note that Russian often pairs this term with measurements (e.g., "коэффициент пористости" for a numerical value). Be cautious with declensions based on sentence structure—always adjust for case to avoid grammatical errors. If multiple translations exist, choose "пористость" for general porosity; use "проницаемость" only if permeability is implied.
Common Errors:
Confusing "пористость" with "проницаемость": Learners might use "проницаемость" (permeability) when "пористость" is needed, as they are related but distinct. Incorrect: "Проницаемость породы высока" (when meaning porosity). Correct: "Пористость породы высока". Explanation: Porosity refers to void spaces, while permeability involves fluid movement through those spaces.
Incorrect declension: For example, using the nominative "пористость" in a genitive context, like "измерение пористость" instead of "измерение пористости". Explanation: Always decline based on the sentence's grammatical requirements to maintain agreement.
Cultural Notes:
While "пористость" itself is a neutral scientific term without strong cultural connotations, it frequently appears in Russian contexts related to natural resources like oil and gas exploration, reflecting Russia's historical emphasis on geology and mining industries. This can highlight how language in technical fields often draws from practical applications in the country's economy.
