Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
Many letters of the Latin alphabet, both capital and small, are used in mathematics, science, and engineering to denote by convention specific or abstracted constants, variables of a certain type, units, multipliers, or physical entities. Certain letters, when combined with special formatting, take on special meaning.
This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa , such ...
See § Brackets for examples of use. Most symbols have two printed versions. They can be displayed as Unicode characters, or in LaTeX format. With the Unicode version, using search engines and copy-pasting are easier. On the other hand, the LaTeX rendering is often much better (more aesthetic), and is generally considered a standard in mathematics.
Frequently used to indicate maternal roles, this word should not be construed as translating directly to "mother" (Latin māter; Ancient Greek μήτηρ mḗtēr); aside from being a proper name, in Ancient Greek "maîa" can translate to "midwife" or "foster mother" and was used as an honorific address for older women, typically translated ...
A feature affecting clarity in seeing a scientific word's components is haplology, i.e. removing one of two identical or similar syllables that meet at the junction point of a compound word. Examples are: appendectomy = appendix, appendicis, (Latin for "appendix") + -ectomy (ultimately from Greek τομή, "a cutting")
Example (in a letter format): "Sincerely, John Smith. PS Tell mother I say hello!" PPS post post scriptum "post-postscript" Used to indicate additions after a postscript. Sometimes extended to comical length with PPPS, PPPPS, and so on. q.d. quaque die "every day" Used on prescriptions to indicate the medicine should be taken daily. QED
