“…Research indicates that, before effectively using explicit techniques like COMPARISON and CATEGORIZATION that are commonly associated with metaphoric language (Gentner & Bowdle, 2008;Glucksberg, 2001), pragmatic conventions are constructed long before actual language in terms of metaphorical thought (e.g., Alessandroni, 2017). In the course of development, children start very early to overextend the meanings of words in order to label things or express (mostly) non-abstract concepts for which they lack literal terms (see, e.g., Clark, 2003;Pérez-Hernández & Duvignau, 2016;Pouscoulous, 2011). Until approximately age four, children use metaphors in the form of overextended meanings of terms already acquired (Nerlich, Clarke, & Todd, 1999), whereas at some point they are able to deliberately extend meanings in order to intentionally overcome literal borders (e.g., Pouscoulous, 2011).…”
