Running title: Informational redundancy and reduction Address correspondence to:

This study investigates the relationship between word repetition, predictability from neighbouring words, and articulatory reduction in Dutch. The focus was on the seven most frequent words ending in the adjectival sufx-lijk. For each of these words, 40 oc-currences were randomly selected from a large database of face-to-face conversations. The selected tokens were manually transcribed and the durations of their stems and sufxes were measured. The results show that the degree of articulatory reduction (as measured by duration and number of realized segments) was indeed affected by repeti-tion, predictability from the previous word, and predictability from the following word. Interestingly, not all of these effects were signicant across morphemes and target words. The implications of these ndings for models of speech production are discussed.
