Prefix (linguistics) in the context of "Anaphrodisiac"

Dominus is the Latin word for Lord or owner. Dominus was used primarily as an imperial title during the era of the Roman Empire (25 BC – 1453 AD) and was also the Latin title of the feudal, superior and mesne, lords. Dominus was also used as an ecclesiastical and academic title during thattime. The ecclesiastical title was translated from the French seigneur into English as sir, making it a common prefix for parsons before the Reformation. This is evident by the character's name Sir Hugh Evans in Shakespeare's Merry Wives of Windsor. The title Dominus is still used in modern times for those with a Bachelor of Arts degree.

The shortened form for Dominus – Dom – has remained in use in modern times as a prefix of honor for ecclesiastics of the Catholic Church, and members of religious orders, especially for those of the monastic Order of Saint Benedict, the Benedictines, who have professed perpetual religious vows. The Spanish equivalents of Doñacode: spa promoted to code: es and the French equivalent of Dame are given to nuns of the Benedictine order.

Al- (Arabic: ٱلْـ, also romanized as el-, il-, and l- as pronounced in some varieties of Arabic), is the definite article in the Arabic language: a particle (ḥarf) whose function is to render the noun on which it is prefixed definite. For example, the word كتاب kitāb "book" can be made definite by prefixing it with al-, resulting in الكتاب al-kitāb "the book". Consequently, al- is typically translated as "the" in English.

Unlike most other Arabic particles, al- is always prefixed to another word and never stands alone. Consequently, many dictionaries do not list it, and it is almost invariably ignored in collation, as it is not an intrinsic part of the word.

A circumfix (abbr: CIRC) (also parafix, confix, or ambifix) is an affix which has two parts, one placed at the start of a word, and the other at the end. Circumfixes contrast with prefixes, attached to the beginnings of words; suffixes, attached at the end; and infixes, inserted in the middle. Circumfixes are common in Malay and Georgian.

Its related operation is called circumfixation (or parafixation, confixation, ambifixation).

Anglo is a prefix indicating a relation to, or descent from England, English culture, the English people or the English language, such as in the term Anglosphere. It is often used alone, somewhat loosely, to refer to people of British descent in Anglo-America, the Anglophone Caribbean, South Africa, Australia, and New Zealand. It is used in Canada to differentiate between Francophone Canadians, located mainly in Quebec but found across Canada, and Anglophone Canadians, also located across Canada, including in Quebec. It is also used in the United States to distinguish the Hispanic and Latino population from the non-Hispanic white majority.

Anglo is a Late Latin prefix used to denote English- in conjunction with another toponym or demonym. The word is derived from Anglia, the Latin name for England and still used in the modern name for its eastern region, East Anglia. It most likely refers to the Angles, a Germanic people originating in the north German peninsula of Angeln, that is, the region of today's Lower Saxony that joins the Jutland Peninsula. The first recorded use of the word in Latin is in Tactitus's Germania, where he mentions the "Angles" as a Suebian tribe living near the Elbe. Bede writes that the Angles came from a place called Angulus "which lies between the province of the Jutes and the Saxons." Anglia and England both mean land of the English.

In chemistry, octahedral molecular geometry, also called square bipyramidal, describes the shape of compounds with six atoms or groups of atoms or ligands symmetrically arranged around a central atom, defining the vertices of an octahedron. The octahedron has eight faces, hence the prefix octa. The octahedron is one of the Platonic solids, although octahedral molecules typically have an atom in their centre and no bonds between the ligand atoms. A perfect octahedron belongs to the point group O_h. Examples of octahedral compounds are sulfur hexafluoride SF₆ and molybdenum hexacarbonyl Mo(CO)₆. The term "octahedral" is used somewhat loosely by chemists, focusing on the geometry of the bonds to the central atom and not considering differences among the ligands themselves. For example, [Co(NH₃)₆], which is not octahedral in the mathematical sense due to the orientation of the N−H bonds, is referred to as octahedral.

The concept of octahedral coordination geometry was developed by Alfred Werner to explain the stoichiometries and isomerism in coordination compounds. His insight allowed chemists to rationalize the number of isomers of coordination compounds. Octahedral transition-metal complexes containing amines and simple anions are often referred to as Werner-type complexes.

A privative, named from Latin privare 'to deprive', is a particle that negates or inverts the value of the stem of the word. In Indo-European languages, many privatives are prefixes, but they can also be suffixes, or more independent elements.
