- Proto-Indo-European root
The roots of the reconstructed
Proto-Indo-European language(PIE) are basic morphemes carrying a lexicalmeaning. By addition of suffixes, they form stems, and by addition of desinences, these form grammatically inflected words ( nouns or verbs).
PIE roots are subject to ablaut, and except for a very few cases, the root is fully characterized by its constituent consonants, while the vowel may alternate. PIE roots as a rule have a single syllabic core, and by ablaut may either be monosyllabic or unsyllabic.
PIE roots may be of the following form (where K is a voiceless stop, G an unaspirated and Gh an aspirated stop, R a sonorant ("r, l, m, n, w, y") and H a fricative (either laryngeal or "s")
A root has at least one consonant, in some theories at least two ("Unicode|*h₁eḱ" vs. "Unicode|eḱ" "quick"). Depending on the interpretation of laryngeals, some roots seem to have an inherent "a" or "o" vowel, "*ar-" (vs. "Unicode|*h₂ar-") "fit", "*Unicode|ongʷ" (vs. "Unicode|*h₃engʷ") "anoint", "Unicode|*bʰag" "consume", "Unicode|*aḱ" (vs. "Unicode|*h₂eḱ") "keen".
By "root extension", a basic CeC (with C being any consonant) pattern may be extended to CeC-C, and an
s mobilemay extend it to s-CeC.
