A fellow or companion; an archaic or dialectal term for a person, often used in Middle English texts.
From Middle English 'fetlow' or 'felow,' a variant of 'fellow' (from Old Norse félagi, meaning comrade or partner). This spelling persisted in some dialects but became archaic by modern English.
This is 'fellow' frozen in medieval spelling—seeing 'fetlow' in old texts is like discovering a word in its awkward teenage years before it settled into the modern form we recognize today.
