Old Pskov dialect

The Old Pskov dialect (Russian: древнепсковский диалект), also known as Old Pskovian, was spoken in the Pskov Republic. It is closely related to the Old Novgorod dialect, which had features that are notably different from other East Slavic varieties. As a result, the two are considered to be subdialects of the same branch. The Novgorod-Pskov dialect is also referred to as (Early) North Russian and Northwest Old Russian.

According to Andrey Zaliznyak, together with the Old Novgorod dialect, it formed a cluster of closely related dialects which converge with the other East Slavic dialects only in the Proto-Slavic stage. For instance, the second regressive palatalization left no traces in the Novgorod-Pskov dialect (e.g. kěle 'whole' as opposed to Old Church Slavonic cělъ).
