In linguistics, feminization has two mutually independent meanings. First, it 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. 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 denoted virtue and vice. 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.
Feminists believe the use of the generic masculine to refer to someone who's gender is unknown erases women and should be abolished. There are a number of arguments against such prescriptive rules however.
Feminization in various languages

Italian

A 2001 study by Mucchi-Faina and Barro showed that women professionals are more persuasive when using the masculine ending while a 2012 study by Merkel et al. show there was no difference in perception.
Noun declension is asymmetrical in Russian. Women can be referred to with suffixes of the first or second declension but men can only be referred to with first declension suffixes.
