<p>In the <i>Oxford English Dictionary</i>, <i>gender</i> is defined as, "[i]n mod[ern] (esp[ecially] feminist) use, a euphemism for the sex of a human being, often intended to emphasize the social and cultural, as opposed to the biological, distinctions between the sexes", with the earliest example cited being from 1963.<sup id="cite_ref-51" class="reference"><a href="#cite_note-51">&#91;51&#93;</a></sup> The <i>American Heritage Dictionary</i> (5th edition) states that <i>gender</i> may be defined by identity as "neither entirely female nor entirely male"; its <i>Usage Note</i> adds:<sup id="cite_ref-ahdictionary.com,_5th_ed_52-0" class="reference"><a href="#cite_note-ahdictionary.com,_5th_ed-52">&#91;52&#93;</a></sup>

<blockquote><p>Some people maintain that the word <i>sex</i> should be reserved for reference to the biological aspects of being male or female or to sexual activity, and that the word <i>gender</i> should be used only to refer to sociocultural roles. ... In some situations this distinction avoids ambiguity, as in <i>gender research</i>, which is clear in a way that <i>sex research</i> is not. The distinction can be problematic, however. Linguistically, there isn't any real difference between <i>gender bias</i> and <i>sex bias</i>, and it may seem contrived to insist that <i>sex</i> is incorrect in this instance.</p></blockquote>

<p>Since the social sciences now distinguish between biologically defined <i>sex</i> and socially constructed <i>gender</i>, the term <i>gender</i> is now also sometimes used by linguists to refer to social gender as well as grammatical gender. Traditionally, however, a distinction has been made by linguists between <i>sex</i> and <i>gender</i>, where <i>sex</i> refers primarily to the attributes of  real-world entities – the relevant extralinguistic attributes being, for instance,  male, female, non-personal, and indeterminate sex – and <a href="/wiki/Grammatical_gender" title="Grammatical gender">grammatical gender</a> refers to a category, such as  masculine, feminine, and neuter (frequently based on sex, but not exclusively so in all languages), that determines the <a href="/wiki/Agreement_(linguistics)" title="Agreement (linguistics)">agreement</a> between nouns of different genders and associated words, such as articles and adjectives.<sup id="cite_ref-Huddleston_on_grammatical_gender_61-0" class="reference"><a href="#cite_note-Huddleston_on_grammatical_gender-61">&#91;61&#93;</a></sup><sup id="cite_ref-Butterfield_on_grammatical_gender_62-0" class="reference"><a href="#cite_note-Butterfield_on_grammatical_gender-62">&#91;62&#93;</a></sup>

Thus <i>Mann</i> (meaning man) is masculine and is associated with a masculine definite article to give <i>der Mann</i>, while <i>Frau</i> (meaning woman) is feminine and is associated with a feminine definite article to give <i>die Frau</i>. However the words for inanimate objects are commonly masculine (e.g. <i>der Tisch</i>, the table) or feminine (<i>die Armbanduhr</i>, the watch), and grammatical gender can diverge from biological sex; for instance the feminine noun <i>[die] Person</i> refers to a person of either sex, and the neuter noun <i>[das] Mädchen</i> means "the girl".

<p>Many <a href="/wiki/Feminist" class="mw-redirect" title="Feminist">feminists</a> consider sex to only be a matter of biology and something that is not about social or cultural construction.

They believe the distinction fails to recognize anything outside the strictly male/female dichotomy and that it creates a barrier between those that fit as 'usual' and those that are 'unusual'.<sup class="noprint Inline-Template" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:Manual_of_Style/Words_to_watch#Unsupported_attributions" title="Wikipedia:Manual of Style/Words to watch"><span title="The material near this tag possibly uses too-vague attribution or weasel words.

In this case, the standard model (sex/gender distinction) is seen as incorrect with regard to its notion that there are only two sexes, male and female. This is because "complete maleness and complete femaleness represent the extreme ends of a spectrum of possible body types."<sup id="cite_ref-86" class="reference"><a href="#cite_note-86">&#91;86&#93;</a></sup> In other words, Fausto-Sterling argues that sex is a continuum.
</p><p>Rather than viewing sex as a biological construct, there are feminists who view both sex and gender as a <a href="/wiki/Social_constructionism" title="Social constructionism">social construct</a>.<sup class="noprint Inline-Template" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:Manual_of_Style/Words_to_watch#Unsupported_attributions" title="Wikipedia:Manual of Style/Words to watch"><span title="The material near this tag possibly uses too-vague attribution or weasel words. (July 2021)">who?</span></a></i>&#93;</sup>  Fausto-Sterling believes that sex is socially constructed because nature does not decide on who is seen as a male or female physically. Rather, doctors decide what seems to be a "natural" sex for the inhabitants of society. In addition, the gender, behavior, actions, and appearance of males/females is also seen as socially constructed because codes of femininity and masculinity are chosen and deemed fit by society for societal usage.
</p><p>Some <a href="/wiki/Feminist_philosophy" title="Feminist philosophy">feminist philosophers</a> maintain that gender is totally undetermined by sex. See, for example, <i><a href="/wiki/The_Dialectic_of_Sex" title="The Dialectic of Sex">The Dialectic of Sex: The Case for Feminist Revolution</a></i>, a widely influential feminist text.<sup id="cite_ref-87" class="reference"><a href="#cite_note-87">&#91;87&#93;</a></sup>
</p><p>Mari Mikkola has put forward the "Trait/Norm Covariance Model" as a suggested replacement for the sex/gender distinction.<sup id="cite_ref-88" class="reference"><a href="#cite_note-88">&#91;88&#93;</a></sup><sup id="cite_ref-89" class="reference"><a href="#cite_note-89">&#91;89&#93;</a></sup><sup id="cite_ref-90" class="reference"><a href="#cite_note-90">&#91;90&#93;</a></sup><sup id="cite_ref-91" class="reference"><a href="#cite_note-91">&#91;91&#93;</a></sup> Arguing that the sex/gender distinction, as formulated in contemporary feminism, implies that "doing away with gender should be feminism's political goal", the model divides by descriptive traits and evaluative norms, rather than by sex and gender. In this model, the term "descriptive traits" includes physical and anatomical traits, roles, and self-conceptions. So for example, "sex traits" (such as having ovaries) and "gender traits" (such as wearing make-up) are both subsumed under the category of descriptive traits, whereas "being feminine" is taken as an evaluative norm. Evaluative norms reflect how descriptive traits are evaluated by external observers, and certain descriptive traits may covary with certain evaluative norms. So for example the trait "having long hair" covaries strongly with feminine norms in some cultures, and less so in others.

<h3><span class="mw-headline" id="Limitations">Limitations</span></h3>
<p>Some feminists go further and argue that neither sex nor gender are strictly binary concepts. <a href="/wiki/Judith_Lorber" title="Judith Lorber">Judith Lorber</a>, for instance, has stated that many conventional indicators of sex are not sufficient to demarcate male from female. For example, not all women lactate, while some men do.<sup id="cite_ref-lorber_92-0" class="reference"><a href="#cite_note-lorber-92">&#91;92&#93;</a></sup> Similarly, <a href="/wiki/Suzanne_Kessler" title="Suzanne Kessler">Suzanne Kessler</a>, in a 1990 survey of medical specialists in pediatric intersexuality, found out that when a child was born with XY chromosomes but ambiguous genitalia, its sex was often determined according to the size of its penis.<sup id="cite_ref-93" class="reference"><a href="#cite_note-93">&#91;93&#93;</a></sup> Thus, even if the sex/gender distinction holds, Lorber and Kessler suggest that the dichotomies of female/male and masculine/feminine are not themselves exhaustive. Lorber writes, "My perspective goes beyond accepted feminist views that gender is a cultural overlay that modifies physiological sex differences ... I am arguing that bodies differ in many ways physiologically, but they are completely transformed by social practices to fit into the salient categories of a society, the most pervasive of which are 'female' and 'male' and 'women' and 'men.'"<sup id="cite_ref-lorber_92-1" class="reference"><a href="#cite_note-lorber-92">&#91;92&#93;</a></sup>
</p><p>Moreover, Lorber has alleged that there exists more diversity within the individual categories of sex and gender—female/male and feminine/masculine, respectively—than between them.<sup id="cite_ref-lorber_92-2" class="reference"><a href="#cite_note-lorber-92">&#91;92&#93;</a></sup> Hence, her fundamental claim is that both sex and gender are social constructions, rather than <a href="/wiki/Natural_kind" title="Natural kind">natural kinds</a>.
</p><p>A comparable view has been advanced by <a href="/w/index.php?title=Linda_Zerilli&amp;action=edit&amp;redlink=1" class="new" title="Linda Zerilli (page does not exist)">Linda Zerilli</a>, who writes regarding <a href="/wiki/Monique_Wittig" title="Monique Wittig">Monique Wittig</a>, that she is "critical of the sex/gender dichotomy in much feminist theory because such a dichotomy leaves unquestioned the belief that there is a 'core of nature which resists examination, a relationship excluded from the social in the analysis—a relationship whose characteristic is ineluctability in culture, as well as in nature, and which is the heterosexual relationship.'"<sup id="cite_ref-94" class="reference"><a href="#cite_note-94">&#91;94&#93;</a></sup> <a href="/wiki/Judith_Butler" title="Judith Butler">Judith Butler</a> also criticizes the sex/gender distinction. Discussing sex as biological fact causes sex to appear natural and politically neutral. However, she argues that "the ostensibly natural facts of sex [are] discursively produced in the service of other political and social interests." Butler concludes, "If the immutable character of sex is contested, perhaps this construct called 'sex' is as culturally constructed as gender; indeed, perhaps it was always already gender, with the consequence that the distinction between sex and gender turns out to be no distinction at all."<sup id="cite_ref-95" class="reference"><a href="#cite_note-95">&#91;95&#93;</a></sup>

This is that the sex cells or 'gametes' of males are much smaller and more numerous than the gametes of females. This is true whether we are dealing with animals or plants. One group of individuals has large sex cells, and it is convenient to use the word female for them. The other group, which it is convenient to call male, has small sex cells. The difference is especially pronounced in reptiles and in birds, where a single egg cell is big enough and nutritious enough to feed a developing baby for several weeks. Even in humans, where the egg is microscopic, it is still many times larger than the sperm. As we shall see, it is possible to interpret all the other differences between the sexes as stemming from this one basic difference.</q></cite><span title="ctx_ver=Z39.88-2004&amp;rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&amp;rft.genre=bookitem&amp;rft.atitle=9+Battle+of+the+Sexes&amp;rft.btitle=The+Selfish+Gene&amp;rft.pages=141&amp;rft.pub=Oxford+University+Press&amp;rft.date=1989&amp;rft_id=info%3Aoclcnum%2F895773595&amp;rft.isbn=978-0-19-286092-7&amp;rft.aulast=Dawkins&amp;rft.aufirst=Richard&amp;rft_id=https%3A%2F%2Fbooks.google.com%2Fbooks%3Fid%3DWkHO9HI7koEC%26pg%3DPA141&amp;rfr_id=info%3Asid%2Fen.wikipedia.org%3ASex+and+gender+distinction" class="Z3988"></span></span>
