Asister is awoman or agirl who sharesparents or a parent with another individual; a femalesibling.[1] The male counterpart is abrother. Although the term typically refers to afamilial relationship, it is sometimes used endearingly to refer to non-familial relationships.[2] A full sister is afirst-degree relative.
TheEnglish wordsister comes fromOld Norsesystir which itself derives fromProto-Germanic*swestēr, both of which have the same meaning, i.e. sister. Some studies have found that sisters display more traits indicating jealousy around their siblings than their male counterparts,brothers.[3] In some cultures, sisters are afforded a role of being under the protection by male siblings, especially older brothers, from issues ranging from bullies or sexual advances by womanizers.[4] In some quarters, the termsister has gradually broadened its colloquial meaning to include individuals stipulatingkinship.[5] In response, in order to avoid equivocation, some publishers prefer the usage offemale sibling oversister.[6] Males with atwin sister sometimes view her as their femalealter ego, or what they would have been like if they had two X chromosomes.[7] A study in Perth, Australia found that girls having only younger brothers resulted in achastity effect: losing theirvirginity on average more than a year later than average. This has been hypothesized as being attributed to the pheromones in their brothers' sweat and household-related errands.[8]
Various studies have shown that older sisters are likely to give a variedgender role to their younger siblings, as well as being more likely to develop a close bond with their younger siblings.[9] Older sisters are more likely to play with their younger siblings.[10] Younger siblings display more needy behavior when near their older sister[11] and are more likely to be tolerant of an older sister's bad behavior.[12] Boys with only one older sister are more likely to display stereotypically male behavior, and suchmasculine boys increased their masculine behavior with the more sisters they have.[13] The reverse is true for young boys with several sisters, as they tend to befeminine, however, they outgrow this by the time they approachpubescence.[14] Boys with older sisters were less likely to be delinquent or haveemotional and behavioral disorders.[15] A younger sister is less likely to be scolded by older siblings than a younger brother.[16] The most common recreational activity between older brother/younger sister pairs is art drawing.[9] Some studies also found a correlation between having an older sister and constructive discussions about safe sexual practices.[17] Some studies have shown that men without sisters are more likely to be ineffectual at courtship and romantic relationships.[18]
