RusTajLexicalCorpus

A parallel lexical corpus for Russian–Tajik language pairs, compiled from authoritative printed dictionaries.

📖 Description

This dataset contains lexical pairs (Russian ↔ Tajik) extracted from two CSV files:

• rus_taj.csv – Russian–Tajik dictionary entries
• taj_rus.csv – Tajik–Russian dictionary entries

The data originates from well‑known academic dictionaries published in the Soviet and post‑Soviet periods. All entries are presented as plain word pairs without additional grammatical or usage annotations in this release.
