D-cedilla (majuscule: Ḑ, minuscule: ḑ) is a letter of the Latin alphabet, consisting of the letter D with a cedilla under it. The letter stands for the voiced palatal plosive in the Livonian alphabet. Before a 1904 spelling reform, the letter was also used in Romanian for the voiced alveolar fricative in Latin-derived words where Latin had used ⟨d⟩ — the reform replaced this with a simple ⟨z⟩; see Obsolete letters of the Romanian alphabet.
