characteristic englanniksi - Sanakirja.org (englanti-englanti)

a distinguishable feature of a person or thing
(mathematics) the integer part of a logarithm
(nautical) the distinguishing features of a navigational light on a lighthouse etc by which it can be identified (colour, pattern of flashes etc)
(algebra, field theory) The minimum number of times that the unit of a field must be added unto itself in order to yield that field's zero, or, if that minimum natural number does not exist, then (the integer) zero.
