Etymology
the word 'futon' entered english as a direct borrowing from japanese in the late 19th century. in japanese, 布団 (futon) is a compound of 布 (fu, meaning 'cloth') and 団 (ton, meaning 'round' or 'group'), originally referring to a round bundle of bedding. the term reflects the traditional japanese bedding system of a padded mattress placed directly on the floor. as western interest in minimalist and japanese-style living grew, the word was adopted into english, where it now specifically denotes a versatile, often foldable, mattress or sofa-bed.
Analysis
this word is a direct loanword from japanese, where it is written as 布団. it is not composed of separable morphemes in english.
Examples
