Background Language profiles may predict whether children with slower language development will catch up to their peers by overcoming this transient phenomenon or will be at risk for persistent language disorders. The research of the last decade has focused on this topic. Some researchers have emphasized the significance of developing communicative intentions, which provide a potential predictor of later language competence. In Turkey, children with slower language development may not be diagnosed partly because of the lack of sufficient standardized assessment/evaluation tools, educational and therapeutic media, and qualified speech-language therapists. In devising appropriate evaluation instruments, it is necessary to examine cross-linguistic variation in early language acquisition. The purpose of this study therefore is to observe, describe and assess early communicative behaviours of 15-36 months old Turkish-speaking children by using a functional communicative approach.
