Pussy is a term used as a noun, an adjective, and—in rare instances—a verb in the English language. It has several meanings, as slang, as euphemism, and as vulgarity. The most common as a noun, it means "cat", as well as "coward or weakling". In slang usage, it can mean "vulva or vagina" and less commonly, as a form of synecdoche, meaning "sexual intercourse with a woman". Because of its multiple senses including both innocent and vulgar connotations, pussy is often the subject of double entendre.
The etymology of the word is not clear. Several different senses of the word have different histories or origins. The earliest records of pussy are in the 19th century, meaning something fluffy.
Etymology
The noun pussy meaning "cat" comes from the Modern English word puss, a conventional name or term of address for a pet cat. The Oxford English Dictionary (OED) says that cognates are common to several Germanic languages, including Dutch poes and Middle Low German pūse, which are also used to call a cat. The word puss is attested in English as early as 1533. Earlier etymology is uncertain, but similar words exist in other European languages, including Lithuanian puižė and Irish puisín, both traditional calls to attract a cat.
The words puss and derived forms pussy and pusscat were extended to refer to girls or women by the seventeenth century. This sense of pussy was used to refer specifically to genitalia by the eighteenth century, and from there further extended to refer to sexual intercourse involving a woman by the twentieth century.
Noah Webster, in his original 1828 American Dictionary of the English Language, defined pussy as: "inflated, swelled; hence, fat, short and thick; and as persons of this make labor in respiration, the word is used for short breathed". He gave pursy as a "corrupt orthography" or misspelling of pussy. In 1913, however, Webster's Revised Unabridged Dictionary reversed the original, suggesting that pussy was a "colloquial or low" variant of pursy. That word, in turn, was defined as "fat and short-breathed", with etymology from Old French pousser "to push". In the Northern English variant of British English, the dialect form pursy, now rare or obsolete, means "fat" or "short-winded".
The Webster's Third International Dictionary points out similarities between pussy in the sense of "vulva" and Low German or Scandinavian words meaning "pocket" or "purse", including Old Norse pūss and Old English pusa.
The medieval French word pucelle, meaning "maiden" or "virgin", is not related to the English word. It is attested in Old French from the ninth century, and likely derives from Latin. The precise Latin source is disputed, with either puella "girl" or pulla "pullet, young female chicken" suggested as earlier sources.
As a homograph, pussy also has the meaning "containing pus"; with this meaning, the word is pronounced , while the other forms are all pronounced .
Meanings of the verb relate to the common noun senses, including "to act like a cat", "to act like a coward", or "to have sex with a woman". Adjective meanings are likewise related to the noun.
Uses
Cat and similar
Both in English and in German puss was used as a "call-name" for cats, but in English pussy was used as a synonym for the word cat in other uses as well. In addition to cats, the word was also used for rabbits and hares. In the 19th century, the meaning was extended to anything soft and furry. Pussy willow, for example, is a name applied to various species in the genus Salix with furry catkins. In thieves' cant the word pussy means a "fur coat".
The Oxford English Dictionary gives as the first meaning of the noun: "Chiefly colloq[uial]. A girl or woman exhibiting characteristics associated with a cat, esp[ecially] sweetness or amiability. Freq[uently] used as a pet name or as a term of endearment." The examples it cites from the mid-19th to mid-20th centuries are not sexual. Another example, not cited by the OED, is one of the main characters of E. Nesbit's Five Children and It - Jane, nicknamed Pussy by her siblings.
The verb pussyfoot, meaning to walk softly or to speak in an evasive or cautious manner, may come from the adjective pussy-footed "having a cat-like foot", or directly from the noun pussyfoot. This word, first attested in the late nineteenth century, is related to both the "cat" and the "woman" meanings of pussy.
