Etymology

Origin of fellow

before 1050; Middle English felowe, felawe, late Old English fēolaga < Old Norse fēlagi partner in a joint undertaking, equivalent to fē money, property (cognate with Old English feoh, German Vieh ) + -lagi bedfellow, comrade; akin to lair ¹, lie ²

Explanation

Fellow is an old fashioned word for “guy.” If you’re wearing a top hat, you may address someone as “my good fellow.” It’s also a non-stuffy word to describe people in the same situation, such as you and your fellow Vocabulary.com fans. Other words for fellow include "chap" and "dude." A fellow can also be someone’s boyfriend, as in “Is he your fellow?” an interested suitor might ask. Another kind of fellow is an academic who's either reached a high position or won a prestigious scholarship. A MacArthur Fellow, for example, is a person who won a MacArthur fellowship (a well-deserved hunk of money). Fellow comes from an Old English word, feolaga, "one who shares with another."
