The article compares the dialogue language used in the respective Hebrew translations of two Arabic plays written in Palestinian vernacular. These translations, made by two different translators, Cohen and Shammas, are analyzed in terms of grammar, sociolinguistic usage, void pragmatic connectors, emotive expressions and poetic elements such as idioms, proverbs and songs. Both translations were found to use authentic Hebrew dialogue language. Cohen’s translation, however, was found to be more fluent than Shammas’, since the former attempted to find Hebrew equivalents to source texts elements using pragmatic translation, while Shammas used a higher register, sometimes inventing Hebrew words. Thus Cohen adhered to an up-to-date norm of Hebrew dialogue usage while Shammas stuck to an older one.
