armchair
UK: ˈɑːm.tʃeə | US: ˈɑːrm.tʃer
n. a comfortable chair with side supports for a person's arms
n. (figurative) theoretical or uninvolved perspective (e.g., "armchair critic")
The word "armchair" is a straightforward compound of "arm" (from Old English earm, meaning "limb") and "chair" (from Old French chaiere, derived from Latin cathedra, meaning "seat"). It literally describes a chair with armrests. The figurative sense ("armchair critic/theorist") emerged in the 19th century, humorously implying someone who offers opinions while comfortably seated rather than engaging practically.
