Languages attested from the 1st century

The Syriac language (SIH-ree-ak; Classical Syriac: ܠܫܢܐ ܣܘܪܝܝܐ, Leššānā Suryāyā), also known natively in its spoken form in early Syriac literature as Edessan (Urhāyā), the Mesopotamian language (Nahrāyā) and Aramaic (Aramāyā), is an Eastern Middle Aramaic dialect. Classical Syriac is the academic term used to refer to the dialect's literary usage and standardization, distinguishing it from other Aramaic dialects also known as 'Syriac' or 'Syrian'. In its West-Syriac tradition, Classical Syriac is often known as leššōnō kṯoḇonōyō (lit. 'the written language or the book language') or simply kṯoḇonōyō, or kṯowonōyō, while in its East-Syriac tradition, it is known as leššānā ʔatīqā (lit. 'the old language') or saprāyā (lit. 'scribal or literary').

British Latin or British Vulgar Latin was the Vulgar Latin spoken in Great Britain in the Roman and sub-Roman periods. While Britain formed part of the Roman Empire, Latin became the principal language of the elite and in the urban areas of the more romanised south and east of the island. In the less romanised north and west it never substantially replaced the Brittonic language of the indigenous Britons. In recent years, scholars have debated the extent to which British Latin was distinguishable from its continental counterparts, which developed into the Romance languages.
