Datapoint Berbice Dutch/Expression of pronominal subjects
Pronominal subjects are frequently omitted in discourse, as are pronominal objects (Kouwenberg 1994: 180f). Nonetheless, pronominal arguments cannot be considered optional: They cannot be omitted in out-of-the-blue sentences, as would be the case in a pro-drop language. In Example 97, the reference of the suppressed subject pronoun is well-established in the preceding discourse. The only cases which can perhaps be considered as involving a truly empty subject are presentational constructions, such as that in Example 106, and the focus construction-following the analysis of Lumsden (1990), who argues that these constructions are biclausal.
