Etymology
The word 'fellow' originates from the Old English 'fēolaga', meaning a partner or shareholder, which itself was borrowed from Old Norse 'félagi', literally "one who lays down property (fé) with another." This Old Norse term is a compound of 'fé' (cattle, property, money) and the Germanic root lag- (to lay down, place). The concept evolved from a specific business partnership to denote companionship and equality. By the late Middle English period, it broadened to refer to a man or boy in general, while also retaining specialized meanings in academic and institutional contexts to signify a member of a shared group or society.
Analysis
The word 'fellow' is a simplex word derived from Old English. Its components are not productively separable in modern English spelling.
