what are compound verbs
A compound verb is usually composed of a preposition and a verb, although other combinations also exist. The term compound verb was first used in publication in Grattan and Gurrey's Our Living Language (1925). From a morphological point of view, some compound verbs are difficult to analyze because several derivations are plausible. Blacklist, for instance, might be analyzed as an adjective+verb compound, or as an adjective+noun compound that becomes a verb through zero derivation.
