In English, a feminine noun always belongs to the personal gender, never the impersonal gender, and within the personal gender contrasts with masculine. Most people who are referred to using feminine nouns are biologically female, though many are not. Feminine nouns are also often used to refer to female animals. The feminine pronouns in English are "she", "her", "hers" and "herself".
Examples include personal names (e.g. "Ruth", "Samantha", and "Victoria"), certain family-related nouns (e.g. "woman", "girl", "mother", "sister", "daughter", "aunt", "niece", etc) and gendered job titles (e.g. "policewoman", "saleswoman", etc). Additionally, some words exclusively refer to female animals and are feminine, e.g. "dam", "ewe", etc.
Gender-neutral language, which uses the common gender to cover feminine, masculine and non-binary is preferred by many especially in formal registers of contemporary English. This is less common however in historical English.
Unlike many other languages, English does not have linguistic concord whereby other words must agree with the gender of the noun.
