The definite article the in English is generally used to encode definiteness, so it can be used to refer back to an antecedent or denote shared experience/knowledge in the given discourse (Lyons, 1999). To illustrate, consider sentence (1). (1) The girl is very slim. In (1), the definite article the conveys the message that both the speaker and the hearer presuppose the existence of a unique individual in the set denoted by the nominal phrase the girl (Ionin et al., 2004). In contrast, the indefinite article (i.e., a and an) usually encodes genericity, and it typically introduces a new entity in the domain of discourse under consideration. The syntactic distribution of the indefinite article a differs from that of an. Specifically, the former often precedes a NP, whose pronunciation begins with a consonant, whereas the latter precedes a NP, whose pronunciation initiates with a vowel.
