eider
C2Formal, Technical, Literary
Definition
Meaning
A large northern sea duck (genus Somateria) whose soft breast feathers (eiderdown) are used for stuffing quilts and pillows.
The commercially valuable soft feathers (down) from this duck, used in luxury bedding and insulated clothing; can also refer to products (e.g., eiderdown) made from these feathers.
Linguistics
Semantic Notes
The word refers primarily to the bird species. In common usage, it is most frequently encountered in the compound noun 'eiderdown', referring to the down-filled duvet. The bird itself is rarely referenced in general conversation outside of ornithological or specific regional (e.g., Icelandic, Scottish) contexts.
Dialectal Variation
British vs American Usage
Differences
Usage is largely identical. 'Eiderdown' is slightly more common in UK English for a specific type of duvet, while US English might more generically use 'comforter' or 'quilt'. The bird name 'eider' is equally specialist in both.
Connotations
Connotes luxury, warmth, and natural materials. In regions where the birds are native (e.g., Scotland, Iceland, Canada), it may also have connotations of local wildlife and traditional harvesting.
Frequency
Very low frequency for 'eider' alone. 'Eiderdown' has moderate, declining frequency as a specific term, often replaced by generic terms like 'duvet'.

FAQ
Frequently Asked Questions
No, it is a low-frequency word. Most English speakers encounter it only in the compound 'eiderdown'.
'Eider' refers to the duck species. 'Eiderdown' refers specifically to the soft feathers (down) from that duck's breast, and by extension, to the duvets or comforters stuffed with it.
It is pronounced /ˈaɪ.də/ in British English and /ˈaɪ.dɚ/ in American English, rhyming with 'rider' without the 'r'.
This is a topic of debate. Traditionally, down is collected from empty nests after the ducklings leave, which can be sustainable. However, modern luxury brands often promote this as an ethical, non-harmful practice, while animal rights groups may critique any commercial use of animal products. It's a subject for personal research and conscience.
