Compounding is a morphological process (Plug, 2003), which is very extensive and productive among the sign languages (Meir, 2012). Combining a several words from a language results in the emergence of a new word – a compound, whose final form emerges by processes of reorganization and restructuring (Meir, 2012). Compound is different from the phrase by duration parameter and specific structural features (Klima and Bellugi, 1979). So far, compounds are not described in HZJ. The goal was to determine whether there are compound in HZJ, spot how they differ from the phrases, and describe their structure. Three deaf adults participated in the study. The test material consisted four tasks which included compounds presented in words, image, and the pairs of sentences with compounds and phrases. The goal was to induce the production of compounds inside and outside of the context of the sentence. Data were analysed by means of descriptive analysis, relying on structural features of compounds from other sign languages. The obtained results show that in general, compounds are part of HZJ. It was shown that compound and phrases in HZJ differ according to the duration parameter. The structural characteristics of the compounds in HZJ showed similarities with other sign languages: the change of the movement, the spread of characteristics from one sign to another, the constancy of the dominant hand and the emergence of the transitional movement. This research contributes to HZJ grammar description through description of structural characteristics of compounds. Observed regularity confirm grammaticality ofHZJ which is confirmed as a complex linguistic system.
