Phrasal verbs and their role in English

Phrasal verbs or particle verbs are one of the most idiosyncratic features of the English language, as well as of other Germanic languages, such as German or Dutch. They pose many problems for non-native speakers, because their meanings have to be learned separately from the meanings of their verbal bases (give vs. give up), given that the union of the two elements of the compound (the verb and the particle) very often gives rise to new non-compositional forms very similar to idioms.
