Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
The following conventions are used: Cognates are in general given in the oldest well-documented language of each family, although forms in modern languages are given for families in which the older stages of the languages are poorly documented or do not differ significantly from the modern languages.
Root extensions are additions of one or two sounds, often plosives, to the end of a root. These extensions do not seem to change the meaning of a root, and often lead to variant root forms across different descendants. The source and function of these extensions is not known. [14] For *(s)tew-'to push, hit, thrust', we can reconstruct: [14]
A classic example of the five grades of ablaut in a single root is provided by the different case forms of two closely related Greek words. In the following table, an acute accent (´) marks the syllable carrying the word stress; a macron (¯) marks long vowels and the syllable in bold is the one illustrating the different vowel gradations.

A root (also known as a root word or radical) is the core of a word that is irreducible into more meaningful elements. [1] In morphology, a root is a morphologically simple unit which can be left bare or to which a prefix or a suffix can attach.
The roots of verbs and most nouns in the Semitic languages are characterized as a sequence of consonants or "radicals" (hence the term consonantal root).Such abstract consonantal roots are used in the formation of actual words by adding the vowels and non-root consonants (or "transfixes") which go with a particular morphological category around the root consonants, in an appropriate way ...
Dimorphic – of two different forms. Ecad – a plant assumed to be adapted to a specific habitat. Ecotone – the boundary that separates two plant communities, generally of major rank – trees in woods and grasses in savanna for example. Ectogenesis – variation in plants due to conditions outside of the plants.
