The article reflects on individual differences of foreign language users from the standpoint of polylingual communication in two related lan-guages (intercommunication), on the basis of the work of Paolo Bal-boni on intercomprehension, intercommunication and useful ap-proaches to foreign language learning. The author attempts to elabo-rate a list of individual characteristics which facilitate intercommunica-tion (a conversation in which the participants speak different, but re-lated languages). The discussion relates to features presented by se-lected authors in the field of foreign language teaching, the European documents on language education (CEFR and FREPA) and to psycho-linguistics. The final part describes the characteristics which favour in-tercommunication.
