Sanaa (, ' , ; Old South Arabian: 𐩮𐩬𐩲𐩥 "Ṣnʿw"), also spelled Sanaʽa or Sana, is the largest city in Yemen and the centre of Sanaa Governorate. The city is not part of the Governorate, but forms the separate administrative district of "Amanat Al-Asemah". Under the Yemeni constitution, Sanaʽa is the capital of the country, although the seat of the Yemeni government moved to Aden, the former capital of South Yemen in the aftermath of the Houthi occupation. Aden was declared as the temporary capital by President Abdrabbuh Mansur Hadi in March 2015.
