Other secondary sources, of lesser value due to extensive phonological changes and relatively limited attestation: Old Irish (AD–850). Tocharian (AD –800 ), underwent large phonetic shifts and mergers in the proto-language, and has an almost entirely reworked declension system. Classical Armenian (AD –1000). Albanian (–current time).
