jats:titleAbstract</jats:title>jats:pThe study investigates semantic development of sublexically modal verbs of transfer,jats:italicthrow</jats:italic>andjats:italicsend</jats:italic>, in English-speaking children. For adults, sublexical modality of these verbs can be seen in the fact that the subevent of transfer of the object to the recipient need not take place in the actual world, e.g.jats:italicMary sent/threw a book to John</jats:italic>does not entail a successful transfer of the book to John. Yet in two experiments (Experiment 1: 3–4 year-olds,jats:italicN</jats:italic> = 59; Experiment 2: 3–6 year olds,jats:italicN</jats:italic> = 120) young English-speaking children often misinterpretedjats:italicMary sent a book to John</jats:italic>as entailing successful transfer. We show that such non-adultlike interpretations were present despite the children’s conceptual ability to entertain possible worlds. We propose that children may initially construct verb meanings on the basis of actual events, and later adjust them to include a modal component.</jats:p>
