Communication with diminutives to young children vs. pets in German, Italian, Lithuanian, Russian, and English

This contribution is dedicated to Steven Gillis with whom we have collaborated since the nineties within the “Crosslinguistic Project on Pre- and Protomorphology in Language Acquisition” on both child speech (CS) and child-directed speech (CDS) and also about the development of diminutives (DIMs). We investigate parallels in the use of DIMs and of hypocoristics (HYPs) between CDS and pet-directed speech (PDS), whereas CS is only marginally dealt with. When relevant, also adult-directed speech (ADS), written or oral (especially from electronic corpora, wherever available) will be compared. The presuppositions of this investigation will be stated at the beginning of the Introduction (§ 1). This involves several innovations (beyond descriptions of new data), when compared with existing literature, relevant to theoretical and typological problem areas. We will show that also in DIMs and HYPs used in CDS and PDS semantics only plays a partial or even marginal role when using more DIMs to communicate with young children and young and/or small pets, because it is more relevant that both younger and smaller pets are emotionally closer to us, which is again a pragmatic factor. In regard to language typology, we will apply our concepts of morphological richness and productivity, as argued for and supported in our previous publications, to CDS and PDS and show that richer and more productive patterns of DIM formation of a language also have a typological impact on more frequent and more productive use both in CDS and PDS. We will also apply our concepts of grading morphosemantic transparency/opacity, as argued for and supported in our previous publications, and we start to show, as al- ready shown for CS, that also in CDS towards young children (and similarly in PDS) more morphosemantically transparent DIMs are used than in ADS. This is also connected to their predominantly pragmatic meanings in CDS and PDS (obviously not exclusively pragmatic as in early CS). The languages and authors were selected according to who among the participants in the Crosslinguistic Project on Pre- and Protomorphology in Language Acquisition had CDS and PDS available, plus Elisa Mattiello who has collected English and Italian PDS data.
