A mother is the female parent of a child. Mothers are women who inhabit or perform the role of bearing some relation to their children, who may or may not be their biological offspring. Thus, dependent on the context, women can be considered mothers by virtue of having given birth, by raising their child(ren), supplying their ovum for fertilisation, or some combination thereof. Such conditions provide a way of delineating the concept of motherhood, or the state of being a mother. Women who meet the third and first categories usually fall under the terms 'birth mother' or 'biological mother', regardless of whether the individual in question goes on to parent their child. Accordingly, a woman who meets only the second condition may be considered an adoptive mother, and those who meet only the third a surrogacy mother.
The above concepts defining the role of mother are neither exhaustive nor universal, as any definition of 'mother' may differ based on how social, cultural, and religious roles are defined. The parallel conditions and terms for males: those who are (typically biologically) fathers do not, by definition, take up the role of fatherhood. Mother and fatherhood are not limited to those who are or have parented. Women who are pregnant may be referred to as expectant mothers or mothers-to-be, though such applications tend to be less readily applied to (biological) fathers or adoptive parents.
The modern English word is from Middle English moder, from Old English mōdor, from Proto-Germanic *mōdēr (cf. East Frisian muur, Dutch moeder, German Mutter), from Proto-Indo-European *méh₂tēr (cf. Irish máthair, Tocharian A mācar, B mācer, Lithuanian mótė). Other cognates include Latin māter, Greek μήτηρ, Common Slavic *mati (thence Russian мать (mat’)), Persian مادر (madar), and Sanskrit मातृ (mātṛ).
Biological motherhood for humans, as in other mammals, occurs when a pregnant female gestates a fertilized ovum (the "egg"). Typically, a fetus develops from the viable zygote, resulting in an embryo. Gestation occurs in the woman's uterus until the fetus (assuming it is carried to term) is sufficiently developed to be born. In humans, gestation is often around 9 months in duration, after which the woman experiences labor and gives birth. This is not always the case, however, as some babies are born prematurely, late, or in the case of stillbirth, do not survive gestation. Usually, once the baby is born, the mother produces milk via the lactation process. The mother's breast milk is the source of antibodies for the infant's immune system and commonly the sole source of nutrition for the first year or more of the child's life.
Mother can often apply to a woman other than the biological parent, especially if she fulfills the main social role in raising the child. This is commonly either an adoptive mother or a stepmother (the biologically unrelated partner of a child's father). The term "othermother" or "other mother" is also used in some contexts for women who provide care for a child not biologically their own in addition to the child's primary mother.
Adoption, in various forms, has been practiced throughout history, even predating human civilization. Modern systems of adoption, arising in the 20th century, tend to be governed by comprehensive statutes and regulations. In recent decades, international adoptions have become more and more common.
Adoption in the United States is common and relatively easy from a legal point of view (compared to other Western countries). In 2001, with over 127,000 adoptions, the US accounted for nearly half of the total number of adoptions worldwide.
A surrogate mother is a woman who bears a child that came from another woman's fertilized ovum on behalf of a couple unable to give birth to children. Thus the surrogate mother carries and gives birth to a child that she is not the biological mother of. Surrogate motherhood became possible with advances in reproductive technologies, such as in vitro fertilization.
Not all women who become pregnant via in vitro fertilization are surrogate mothers. Surrogacy involves both a genetic mother, who provides the ovum, and a gestational (or surrogate) mother, who carries the child to term.
Motherhood in same-sex relationships
The possibility for lesbian and bisexual women in same-sex relationships (or women without a partner) to become mothers has increased over the past few decades[when?] due to technological developments. Modern lesbian parenting (a term that somewhat erases the bisexual case) originated with women who were in heterosexual relationships who later identified as lesbian or bisexual, as changing attitudes provided more acceptance for non-heterosexual relationships. Another way for such women to become mothers is through adopting or foster parenting. There is also the option of self-insemination and clinically assisted donor insemination, forms of artificial insemination. As fertility technology has advanced, more females not in a heterosexual relationship have become mothers through in vitro fertilization.
The social roles associated with motherhood are variable across time, culture, and social class.  Historically, the role of women was confined to some extent to being a mother and wife, with women being expected to dedicate most of their energy to these roles, and to spend most of their time taking care of the home. In many cultures, women received significant help in performing these tasks from older female relatives, such as mothers in law or their own mothers.
Regarding women in the workforce, mothers often entail a mommy track rather than being entirely "career women". Mothers may be stay at home mothers or working mothers. In recent decades there has been an increase in stay at home fathers too. Social views on these arrangements vary significantly by culture: in Europe for instance, in German-speaking countries there is a strong tradition of mothers exiting the workforce and being homemakers. Mothers have historically fulfilled the primary role in raising children, but since the late 20th century, the role of the father in child care has been given greater prominence and social acceptance in some Western countries. The 20th century also saw more and more women entering paid work.
The social role and experience of motherhood varies greatly depending upon location. Mothers are more likely than fathers to encourage assimilative and communion-enhancing patterns in their children. Mothers are more likely than fathers to acknowledge their children's contributions in conversation. The way mothers speak to their children ("motherese") is better suited to support very young children in their efforts to understand speech (in context of the reference English) than fathers.
Since the 1970s, in vitro fertilization has made pregnancy possible at ages well beyond "natural" limits, generating ethical controversy and forcing significant changes in the social meaning of motherhood. This is, however a position highly biased by Western world locality: outside the Western world, in-vitro fertilization has far less prominence, importance or currency compared to primary, basic healthcare, women's basic health, reducing infant mortality and the prevention of life-threatening diseases such as polio, typhus and malaria.
Traditionally, and still in most parts of the world today, a mother was expected to be a married woman, with birth outside of marriage carrying a strong social stigma. Historically, this stigma not only applied to the mother, but also to her child. This continues to be the case in many parts of the developing world today, but in many Western countries the situation has changed radically, with single motherhood being much more socially acceptable now. For more details on these subjects, see Legitimacy (family law) and single parent.
The total fertility rate (TFR), that is, the number of children born per woman, differs greatly from country to country. The TFR in 2013 was estimated to be highest in Niger (7.03 children born per woman) and lowest in Singapore (0.79 children/woman).
Health and safety issues
A maternal death is defined by WHO as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes".
In 2006, the organization Save the Children has ranked the countries of the world, and found that Scandinavian countries are the safest places to give birth, whereas countries in sub-Saharan Africa are the least safe to give birth. This study argues a mother in the bottom ten ranked countries is over 750 times more likely to die in pregnancy or childbirth, compared to a mother in the top ten ranked countries, and a mother in the bottom ten ranked countries is 28 times more likely to see her child die before reaching their first birthday.
The most recent data suggests that Italy, Sweden and Luxembourg are the safest countries in terms of maternal death and Afghanistan, Central African Republic and Malawi are the most dangerous.
Childbirth is an inherently dangerous and risky procedure, subject to many complications. The "natural" mortality rate of childbirth—where nothing is done to avert maternal death—has been estimated as being 1500 deaths per 100,000 births. Modern medicine has greatly alleviated the risk of childbirth. In modern Western countries the current maternal mortality rate is around 10 deaths per 100,000 births.
Nearly all world religions define tasks or roles for mothers through either religious law or through the glorification of mothers who served in substantial religious events. There are many examples of religious law relating to mothers and women.
Major world religions which have specific religious law or scriptural canon regarding mothers include: Christianity, Judaism, and Islam. Some examples of honoring motherhood include the Madonna or Blessed Virgin Mother Mary for Catholics, and the multiple positive references to active womanhood as a mother in the book of Proverbs.
In modern cultures, matricide (the killing of one's mother) and filicide (the killing of one's son or daughter) have been studied but remain poorly understood. Psychosis and schizophrenia are common causes of both, and young, indigent mothers with a history of domestic abuse are slightly more likely to commit filicide. Mothers are more likely to commit filicide than fathers when the child is 8 years old or younger. Matricide is most frequently committed by adult sons.
In the United States in 2012, there were 130 matricides (0.4 per million people) and 383 filicides (1.2 per million), or 1.4 incidents per day.
Mothers in art
Throughout history mothers with their children have often been the subject of artistic works, such as paintings, sculptures or writings.
Paintings of mothers with their children have a long tradition in France. In the 18th century, these works embodied the Enlightenment's preoccupation with strong family bonds and the relation between mothers and children.
At the end of the nineteenth century, Mary Cassatt was a painter well known for her portraits of mothers.
Many contemporary movies portray mothers.
Synonyms and translations
The proverbial "first word" of an infant often sounds like "ma" or "mama". This strong association of that sound with "mother" has persisted in nearly every language on earth, countering the natural localization of language.
