While speed is a secondary parameter in some associated motion systems, some languages have verbal affixes dedicated to the encoding of speed – celerative markers. Celeratives can encode both quick and slow speed and are in some languages even the main or the sole way of expressing this meaning. However, some morphemes not only encode speed, but also other types of action manner , in particular hurry or suddenness, following colexification patterns also observed in the lexicon crosslinguistically. This paper provides a first overview of this category in the world’s languages, and more generally suggests that action manner constitutes a set of comparative concepts that can be be encoded morphologically.
