Particles - On the Syntax of Verb-Particle, Triadic and Causative Constructions
Particles are words that do not change their form through inflection and do not fit easily into the established system of parts of speech. Examples include the negative particle "not," the infinitival particle "to" (as in "to go"), and do and let in "do tell me" and "let's go." Particles investigates the constraints on the distribution and placement of verbal particles. A proper understanding of these constraints yields insight into the structure of various secondary predicative constructions.
