C1/C2technical/poetic
Definition
Meaning
A type of grass, typically of the genera Stipa, Achnatherum, or similar, characterized by long, feathery awns or seed heads.
Used poetically or descriptively to refer to any grass with a soft, feathery appearance, especially when backlit by the sun or moving in the wind.
Linguistics
Semantic Notes
Primarily a technical botanical term in ecology, horticulture, and geography. Can be used in poetic or descriptive nature writing to evoke imagery of prairies, steppes, or wild meadows.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. The term is used in relevant technical contexts in both varieties. In the US, associated with specific species like 'Needle-and-Thread Grass' in prairie contexts. In the UK, more likely encountered in botanical texts or descriptions of imported ornamental grasses.
Connotations
Both: technical, botanical, ecological, naturalistic.
Frequency
Low frequency in general language in both varieties. Higher relative frequency in American English due to the presence of native species in prairie/steppe ecosystems.

Translation Traps (for Russian speakers)
- Direct translation "перьевая трава" is understandable but non-standard. The correct Russian term is "ковыль" (kovyl').
- Avoid calquing; use the specific Russian botanical term.
Common Mistakes
- Spelling as 'feathergrass' (should be two words or hyphenated 'feather-grass').
- Using it as a general term for any tall grass.
- Mispronouncing 'feather' with a /θ/ sound (as in 'thick') instead of /ð/ (as in 'the').

FAQ
Frequently Asked Questions
It is most commonly written as two separate words. The hyphenated form 'feather-grass' is also acceptable, especially when used as a compound modifier (e.g., 'feather-grass meadow').
While it may be understood descriptively, it is technically incorrect. 'Feather grass' refers specifically to grasses of certain genera (like Stipa) with distinctive feathery seed heads, not just any tall grass.
It is characteristic of temperate grassland biomes, such as the steppes of Eurasia, the prairies of North America, and the pampas of South America.
Yes. Ecologically, it is a keystone species in grassland ecosystems, providing food and habitat for wildlife and helping to prevent soil erosion.
