In linguistics, feminization refers to the process of re-classifying nouns and adjectives which as such refer to male beings, including occupational terms, as feminine. This is done most of the time by adding inflectional suffixes denoting a female (such as the standard suffix -ess in English, or its equivalent -a in Spanish).
In some languages with grammatical gender, for example Dutch, there is a tendency to assign the feminine gender to certain – in particular abstract – nouns which are originally masculine or neuter. This also happened to some words in Middle English (which, in contrast to Modern English, had grammatical gender) which denoted virtue and vice.[1] In Modern English, in spite of it being a gender-neutral language, certain non-human things that are usually neuter are still sometimes feminized by way of figure of speech, especially countries and ships (see also Gender in English § Ships, Gender in English § Modern English).
Feminization is also related to neutralization, which is the process of replacing masculine forms of words (i.e. policeman) with gender-unmarked forms (i.e. police officer).[2]
Not to be confused with feminization in sociology, though the two subjects are inter-related.
