Addition, restriction, iteration


 Conditional clauses in Dutch can be accompanied by focus particles, as in zelfs als ‘even if’ and
 alleen als ‘only if’. The literature focuses on these additive and restrictive particles, because they may
 influence the truth-conditional meaning of the sentence, which is uncommon for particles. Most of these studies are not based on
 empirical language data, or draw largely from formal written texts in English. This study investigates which focus particles occur
 in Dutch conditionals, and to which extent their uses are associated with spoken and written modes and with formal and informal
 registers. It is shown that restrictive and additive particles are most frequent in formal written texts, and that a third type of
 particle exists, which adds iterative meaning to the conditional, as in telkens als ‘evertime if [when]’. The
 results show this type of particles to be associated with informal spoken texts.
