In the terminology used to discuss the grammar of the Semitic languages, a triliteral is a root containing a sequence of three consonants (so also known as a triconsonantal root). The majority of consonantal roots in these languages are generally triliterals (but some may be quadriliterals). Such abstract consonantal roots are used in the derivation of actual words by adding the vowels and non-root consonants which go with a particular morphological category around the root consonants, in an appropriate way. 14th century BC diplomatic letter in Akkadian, found in Tell Amarna. ... In the terminology used to discuss the grammar of the Semitic languages, a quadriliteral is a consonantal root containing a sequence of four consonants (instead of three consonants, as is more often the case). ...
For example, the following are some of the forms which can be derived from the triconsonantal root k-t-b (general overall meaning "to write") in Hebrew and Arabic:
"he corresponded" (Hebrew), "he asked (someone) to write (something), had a copy made" (Arabic)
3rd. masc. sing. imperfect
yitkattebh יתכתב
yastaktibu يستكتب
(imperfect of above)
Noun with m- prefix and original short vowels:
singular
mikhtabh מכתב
maktab مكتب
"letter" (Hebrew), "office" (Arabic)
Note: The Hebrew fricatives transcribed as "kh" and "bh" above are single phonetic sounds, which can also be transcribed in a number of other ways, such as "ch" and "v" (Eastern-European influenced) or [x] and [β] (IPA). They are transcribed "kh" and "bh" on this page to retain the connection with the pure consonantal root k-t-b.
In Hebrew grammatical terminology, the word Binyan (plural Binyanim) is used to refer to a verb stem or overall verb derivation pattern, while the word Mishqal (or Mishkal) is used to refer to a noun derivation pattern, and these words have gained some use in English-language linguistic terminology. Hebrew grammar is mostly analytical, expressing such forms as dative, ablative, and accusative using prepositional particles rather than morphological cases. ... Arabic is a Semitic language. ... The International Phonetic Alphabet (IPA) is a system of phonetic notation devised by linguists to accurately and uniquely represent each of the wide variety of sounds (phones or phonemes) used in spoken human language. ...
Consonants in triconsonantal clusters were not realized any shorter than in biconsonantal clusters, i.e., the locality effect observed in the onset clusters also applied to codas.
Triconsonantal clusters were again shown to be compositional with respect to duration.
For triconsonantal clusters, preceding vowel length did not have an effect on the duration of the cluster (although no statistics were provided except for mean values).
Naracze is characterized by triconsonantal morphology, which I borrowed from the Semitic languages.
Triconsonantal morphology takes this idea to extremes: the majority of words in Naracze can be derived in a regular fashion from a root (like "dream" in the example above) of three consonants (hence "triconsonantal"), to which affixes are added to derive particular forms.
Certain words in Naracze don't fit neatly into the triconsonantal morphology scheme.
