ORIGIN
Old English (ge)recenian ‘recount, relate’, of West Germanic origin; related to Dutch rekenen and German rechnen ‘to count (count up)’. Early senses included ‘give an account of items received’ and ‘mention things in order’, which gave rise to the notion of ‘calculation’ and hence of ‘being of an opinion’.
