An Etymological Dictionary of the German Language/lateinisch
lateinisch, adj., ‘Latin,’ with the foreign accent, in contrast to the E. term. The diphthong of the second syllable proves that the adj. was naturalized previous to ModHG. MidHG. latînisch, OHG. latînisc, which was adopted in the OHG. period, as is proved by the non-permutation of t (latînus) to HG. ȥȥ, was used chiefly in the monastic schools, in which Latin was cultivated as the language of the Church.
