Ma'anar ƙamus na "zina" shine sanya wani abu marar tsarki ko maras kyau ta hanyar ƙara wani abu a cikinsa, sau da yawa ta hanyar yaudara ko mara izini. Ana amfani da wannan kalmar yawanci don bayyana aikin ƙara wani abu mai cutarwa ko ƙasa da samfur, kamar abinci ko abin sha, don ƙara riba ko yaudarar masu amfani. Zina kuma tana iya komawa ga canza wani abu ko karyata wani abu, kamar takarda ko sakamakon gwaji, don yaudara ko yaudarar wasu.
