partner: [14] Partner is related to part – but not quite so directly as might appear. When it first entered the language it was in the form parcener [13], which remains in existence as a legal term meaning ‘joint heir’. This came via Anglo- Norman parcener ‘partner’ from Vulgar Latin *partiōnārius, a derivative of Latin partītiō ‘partition’ (source of English partition [15]). This in turn was based on the verb partīrī ‘divide up’, a derivative of pars ‘part’. The change from parcener to partner began in the 14th century, prompted by the similarity to part. => part, partition
partner (n.)

Form in English influenced by part (n.). The word also may represent Old French part tenour "part holder."
