A dental consonant is a consonant articulated with the tongue against the upper teeth, such as , , , and in some languages. Dentals are primarily distinguished from sounds in which contact is made with the tongue and the gum ridge, as in English (''see'' Alveolar consonant), due to the acoustic similarity of the sounds and the fact that in the Roman alphabet they are generally written using the same symbols (''t'', ''d'', ''n'', and so on). In the International Phonetic Alphabet, the diacritic for dental consonant is . ==Dentals cross-linguistically== For many languages, such as Albanian, Irish or Russian, velarization is generally associated with more dental articulations of coronal consonants so that velarized consonants (such as Albanian ) tend to be dental or denti-alveolar, whereas non-velarized consonants tend to be retracted to an alveolar position. Sanskrit, Hindi and all other Indic languages have an entire set of dental stops that occur phonemically as voiced and voiceless, and with or without aspiration. The nasal also exists in these languages, but is quite alveolar and apical in articulation. To the Indian speaker, the alveolar and of English sound more like the corresponding retroflex consonants of his own language than like the dentals. Spanish and are laminal denti-alveolar, whereas and are prototypically alveolar but assimilate to the place of articulation of a following consonant. Likewise, Italian , , , are denti-alveolar (, , , and respectively) and and become denti-alveolar before a following dental consonant. Although denti-alveolar consonants are often described as dental, it is the rear-most point of contact that is most relevant, for this is what defines the maximum acoustic space of resonance and will give a consonant its characteristic sound. In the case of French, the rear-most contact is alveolar or sometimes slightly pre-alveolar. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dental consonant」の詳細全文を読む スポンサード リンク
