Numerical prefixes for multiplication of compound or complex (as in complicated) features are created by adding kis to the basic numerical prefix, with the exception of numbers 2 and 3, which are bis- and tris-, respectively.
Systematic names and words comprising SI prefixes and binary prefixes are not hyphenated, by definition. Nonetheless, for clarity, dictionaries list numerical prefixes in hyphenated form, to distinguish the prefixes from words with the same spellings (such as duo-and duo). Several technical numerical prefixes are not derived from words for numbers.
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.
The following is an alphabetical list of Greek and Latin roots, stems, and prefixes commonly used in the English language from A to G. See also the lists from H to O and from P to Z . Some of those used in medicine and medical technology are not listed here but instead in the entry for List of medical roots, suffixes and prefixes .
Different side-chains and functional groups will be grouped together in alphabetical order. (The multiplier prefixes di-, tri-, etc. are not taken into consideration for grouping alphabetically. For example, ethyl comes before dihydroxy or dimethyl, as the "e" in "ethyl" precedes the "h" in "dihydroxy" and the "m" in "dimethyl" alphabetically.
Di, a prefix used in organic chemistry nomenclature; Didymium, a mixture of the elements praseodymium and neodymium once thought to be an element; Diopside, a clinopyroxene mineral; Band 3, a protein; Deionized water, a type of water deprived of the dissolved impurities of ionic nature; Diabetes insipidus, a disease
Thio- can be prefixed with di-and tri-in chemical nomenclature. The word derives from Ancient Greek θεῖον (theîon) 'sulfur' (which occurs in Greek epic poetry as θέ(ϝ)ειον, théweion and may come from the same root as Latin fumus (Indo-European dh-w) and may have originally meant "fumigation substance".)
Adding a prefix to the beginning of an English word changes it to a different word. For example, when the prefix un-is added to the word happy, it creates the word unhappy. The word prefix is itself made up of the stem fix (meaning "attach", in this case), and the prefix pre-(meaning "before"), both of which are derived from Latin roots.
