chlorine

chlorine
\ \ [19] Chlorine is a greenish-yellow gas, and was named for its colour. The term was coined by the British chemist Sir Humphry Davy in 1810, from the Greek khlōrós ‘greenishyellow’.
\ \ Of other words containing this element, chlorophyll [19] too was based on the notion of colour (in reference to the green colouring matter of leaves: the Greek elements literally mean ‘green leaf’), but chloroform [19], originally French, is a secondary formation based ultimately on chlorine (since it was originally regarded as a trichloride of formyl).
\ \ Cf.⇒ YELLOW
