I want to refer to all of the covers that belong to the bed and its accompanying such as pillows, blanket etc. Are these 3 words that I mentioned above can meet my need?
- Bedclothes is literary and/on a general term for everything on a bed. It is rather literary or journalistic.
- Linens is all the sheets and pillow cases and towels. Typically, hotels provide fresh linens daily. [they change the sheets/pillowcases and put out clean towels]. Linens can also include linen tablecloths, for example.
- Bedding refers to the actual stuff a bed is made of and more commonly is used to describe the straw put in barns etc. for an animal to sleep. A dog can also have bedding, made of blankets, for example. It can also refer to the materials mattresses are made up: foam bedding. But it is not used to refer to what one's has in one's linen cupboard for use on beds.
- Bed linens is also a term, which I just remembered. It is usual, elegant and to the point.
Indeed bedding and bedclothes are synonyms, as indicated by Dictionary.com. I found a lot more advertisements selling these items in a web search for "bedding" than "bedclothes," but that may just indicate that "bedclothes" is more common in commerce.
The other term you may be looking for is bed linen. Again from Dictionary.com,
- sheets and pillowcases.
As noted by Merriam-Webster, the term is sometimes bed linens (plural).
According to the definitions given in those sources, however, bed linen does not include blankets or comforters.
