Big O notation
In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.

Blood type
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteinscarbohydratesglycoproteins, or glycolipids, depending on the blood group system. Some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens can stem from one allele (or very closely linked genes) and collectively form a blood group system. Blood types are inherited and represent contributions from both parents. A total of 33 human blood group systems are now recognized by the International Society of Blood Transfusion (ISBT). The two most important ones are ABO and the RhD antigen; they determine someone's blood type (A, B, AB and O, with + and - denoting RhD status).

Breve
A breve (, less often ; ; from the Latin brevis “short, brief”) is the diacritic mark ˘, shaped like the bottom half of a circle. As used in Ancient Greek, it is also called vrachy or brachy.

Caron
A caron ( ˇ ) or háček (; from Czech háček ), also known as a wedge, inverted circumflex, inverted hat, is a diacritic placed over certain letters to indicate present or historical palatalizationiotation, or postalveolar pronunciation in the orthography of some BalticSlavicFinno-Lappic, and other languages. The caron also indicates the third tone (falling and then rising) in the Pinyin romanization of Mandarin Chinese.

Circumflex
The circumflex is a diacritic in the LatinGreek and Cyrillic scripts that is used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from Latin circumflexus "bent around"a translation of the Greek περισπωμένη (perispōménē). The circumflex in the Latin script is chevron-shaped ( ˆ ), while the Greek circumflex may be displayed either like a tilde ( ˜ ) or like an inverted breve (   ̑ ).

Diethyl ether
Diethyl ether, also known as ethoxyethane, ethyl ether, sulfuric ether, or simply ether, is an organic compound in the ether class with the formula . It is a colorless, highly volatile flammable liquid. It is commonly used as a solvent and was once used as a general anesthetic.

Double acute accent
The double acute accent ( ˝ ) is a diacritic mark of the Latin script. It is used primarily in written Hungarian, and consequently is sometimes referred to by typographers as Hungarumlaut, a portmanteau of Hungarian umlaut. The signs formed with diacritic marks are letters in their own right in the Hungarian alphabet (for instance, they are separate letters for the purpose of collation).

Emoticon
An emoticon (short for emotion icon) is a metacommunicative pictorial representation of a facial expression which in the absence of body language and prosody serves to draw a receiver's attention to the tenor or temper of a sender's nominal verbal communication, changing and improving its interpretation. It expresses — usually by means of punctuation marks (though it can include numbers and letters) — a person's feelings or mood. Emoticons are usually sideways to the text. As social media has become widespread, emoticons have played a significant role in communication through technology. They offer another range of "tone" and feeling through texting that portrays specific emotions through facial gestures while in the midst of cyber communication.

Empty set
In mathematics, and more specifically set theory, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set; in other theories, its existence can be deduced. Many possible properties of sets are trivially true for the empty set.

List of emoticons
This is a list of notable and commonly used emoticons or textual portrayals of a writer's mood or facial expression in the form of icons. The Western use of emoticons is quite different from Eastern usage, and Internet forums, such as 2channel, typically show expressions in their own ways. In recent times, graphic representations, both static and animated, have taken the place of traditional emoticons in the form of icons. These are commonly known as emoji.

Macron
A macron is a diacritical mark, a straight bar placed above a letter, usually a vowel. Its name derives from the Greek makrón meaning "long" and was originally used to mark long or heavy syllables in Greco-Roman metrics. It now more often marks a long vowel. In the International Phonetic Alphabet, the macron is used to indicate a mid-tone; the sign for a long vowel is instead a modified triangular colon .

Object file
An object file is a file containing object code, meaning relocatable format machine code that is usually not directly executable. Object files are produced by an assemblercompiler, or other language translator, and used as input to the linker, which in turn typically generates an executable or library by combining parts of object files. There are various formats for object files, and the same object code can be packaged in different object files.

Ogonek
The ogonek (Polish: , "little tail", the diminutive of ogon; ) is a diacritic hook placed under the lower right corner of a vowel in the Latin alphabet used in several European languages, and directly under a vowel in several American Indian languages.
