tell: [OE] Tell goes back to a prehistoric Germanic *taljan, a derivative of *talō ‘something told’ (from which English gets tale). This in turn was formed from the base *tal-, source also of English talk. Beside ‘narrative, discourse’ lies another strand of meaning, ‘counting, enumeration’ (pointing back to an original common denominator ‘put in order’), which survives in all told and the derivative teller ‘counter of votes’, and also in the related German zählen ‘count’.
