A reason for dread or apprehension:
(Gram.) The formal classification by which nouns are grouped and inflected, or changed in form, so as to reflect certain syntactic relationships: pronouns, modifiers, and verbs may also be so inflected: although gender is not a formal feature of English, some nouns and the third person singular pronouns are distinguished according to sex or the lack of sex (Ex.: man or he, masculine gender; woman or she, feminine gender; door or it, neuter gender): in most Indo-European languages, as well as in many others, gender is not necessarily correlated with sex
