(linguistics) One of fourteen Arabic letters that cause the L of a preceding definite article اَل (al-) to be assimilated in pronunciation. The sun letter suppresses the sound of the L and then geminates: al + ṣīn = aṣ-ṣīn. The effect of the sun letter is limited to pronunciation and does not affect the spelling, except that a shadda may be written over the sun letter and in the fully vocalised spelling lām lacks any diacritics: الصِّين (aṣ-ṣīn). The fourteen sun letters are ت (t), ث (ṯ), د (d), ذ (ḏ), ر (r), ز (z), س (s), ش (š), ص (ṣ), ض (ḍ), ط (ṭ), ظ (ẓ), ل (l), ن (n). Phonetically, they represent coronal consonants.

日本語の意味

アラビア語における『sun letter』、すなわち定冠詞「al-」の「l」音が特定の子音（太陽文字）のために同化し、発音上変化を起こす14の文字の総称。これらの文字は本来の発音の中で「l」音を抑制し、重複発音（重子音化）を引き起こす特徴がある。
