The ainoi or praises are the rough Byzantine equivalent to the Western Rite service of Lauds, though instead of being a stand-alone service, they are a portion of the end of Orthros, the primary morning office. The term ainoi comes from the repeated "praise" verses in Psalms 148-150, which make up the bulk of the ainoi. The ainoi begin after the exaposteilaria and end before the doxology.
