Slavs; Slavonic languages in relation to others.
[Medieval Latin Sclavus.]
This form is uncommon. An example is Slavophile, someone favourable or friendly to Slavs. Hyphenated examples usually refer to the Slavonic language group in connection with another language or language group, such as Slavo-Germanic or Slavo-Lithuanian. The Latin root is also the source of slave, since Slav peoples had been reduced to that status in the ninth century.
