Vowels The vowel system includes five long vowels, and two short vowels, (on this page, is used to represent
IPA ). Some of the vowels have more open "emphatic" allophones that occur immediately before emphatic consonants, subject to dialectal variation. These allophones include for and (although may be less open), for and (although may be less open), and for . Karl Prasse argued that /e/ goes back to
Proto-Berber, while /o/ is derived from /u/. Comparative evidence shows that /ə/ derives from a merger of Proto-Berber */ĭ/ and */ŭ/. Sudlow classes the "semivowels" /w, j/ with the vowels, and notes the following possible diphthongs: /əw/ (> [u]), /ăw/, /aw/, /ew/, /iw/, /ow/, /uw/, /əj/ (> [i]), /ăj/, /aj/, /ej/, /ij/, /oj/, /uj/.
Consonants The consonant inventory largely resembles Arabic: differentiated voicing; uvulars, pharyngeals (traditionally referred to as emphatics) ; requiring the pharynx muscles to contract and influencing the pronunciation of the following vowel, and no
voiceless bilabial plosive. The
glottal stop is non-phonemic. It occurs at the beginning of vowel-initial words to fill the place of the initial consonant in the syllable structure (see below), although if the words is preceded by a word ending in a consonant, it makes a
liaison instead. Phrase-final /a/ is also followed by a phonetic
glottal stop. Gemination is contrastive. Normally becomes , becomes , and becomes . and are predominantly geminate. In addition, in Tadɣaq is usually geminate, but in Tudalt singleton may occur. Voicing assimilation occurs, with the first consonant taking the voicing of the second (e.g. > ).
Cluster reduction turns word/morpheme-final into and into (e.g. > 'Tamasheq').
Phonotactics Syllable structure is CV(C)(C), including
glottal stops (see above).
Suprasegmentals Contrastive stress may occur in the stative aspect of verbs.
Dialectal differences Different dialects have slightly different consonant inventories. Some of these differences can be
diachronically accounted for. For example, Proto-Berber
*h is mostly lost in Ayer Tuareg, while it is maintained in almost every position in Mali Tuareg. The Iwellemmeden and Ahaggar Tuareg dialects are midway between these positions. The Proto-Berber consonant
*z comes out differently in different dialects, a development that is to some degree reflected in the dialect names. It is realized as
h in Tamahaq (Tahaggart), as
š in Tamasheq and as simple
z in the Tamajaq dialects Tawallammat and Tayart. In the latter two,
*z is realised as
ž before palatal vowels, explaining the form
Tamajaq. In Tawallammat and especially Tayart, this kind of palatalization actually does not confine itself to
z. In these dialects, dentals in general are palatalized before and . For example,
tidət is pronounced in Tayart. Other differences can easily be traced back to borrowing. For example, the Arabic pharyngeals
ħ and
ʻ have been borrowed along with Arabic loanwords by dialects specialized in Islamic (
Maraboutic) learning. Other dialects substitute
ħ and
ʻ respectively with
x and
ɣ. ==Grammar==
