Phrasal Verbs

In English, a phrasal verb is a phrase such as turn down or ran into which combines two or three words from different grammatical categories: a verb and a particle and/or a preposition together form a single semantic unit. This semantic unit cannot be understood based upon the meanings of the individual parts, but must be taken as a whole. In other words, the meaning is non-compositional and thus unpredictable. Phrasal verbs that include a preposition are known as prepositional verbs and phrasal verbs that include a particle are also known as particle verbs. Additional alternative terms for phrasal verb are compound verb, verb-adverb combination, verb-particle construction, two-part word/verb, and three-part word/verb (depending on the number of particles), and multi-word verb.

Examples

There are at least three main types of phrasal verb constructions depending on whether the verb combines with a preposition, a particle, or both. The phrasal verb constructions in the following examples are in bold:

Verb + preposition (prepositional phrasal verbs)

When the element is a preposition, it is the head) of a full prepositional phrase and the phrasal verb is thus a prepositional phrasal verb. These phrasal verbs can also be thought of as transitive and non-separable; the complement follows the phrasal verb.

• Who is looking after the kids? – after is a preposition that introduces the prepositional phrase after the kids.
• They picked on nobody. – on is a preposition that introduces the prepositional phrase on nobody.
• I ran into an old friend. – into is a preposition that introduces the prepositional phrase into an old friend.
• She takes after her mother. – after is a preposition that introduces the prepositional phrase after her mother.
• Sam passes for a linguist. – for is a preposition that introduces the prepositional phrase for a linguist.
• You should stand by your friend. – by is a preposition that introduces the prepositional phrase by your friend.

Verb + particle (particle phrasal verbs)

When the element is a particle, it can not (or no longer) be construed as a preposition, but rather is a particle because it does not take a complement. These verbs can be transitive or intransitive. If they are transitive, they are separable.

• They brought that up twice. – up is a particle, not a preposition.
• You should think it over. – over is a particle, not a preposition.
• Why does he always dress down? – down is a particle, not a preposition.
• You should not give in so quickly. – in is a particle, not a preposition.
• Where do they want to hang out? – out is a particle, not a preposition.
• She handed it in. – in is a particle, not a preposition. *

Verb + particle + preposition (particle-prepositional phrasal verbs)

Finally, many phrasal verbs are combined with both a preposition and a particle.

• Who can put up with that? – up is a particle and with is a preposition.
• She is looking forward to a rest. – forward is a particle and to is a preposition.
• The other tanks were bearing down on my panther. – down is a particle and on is a preposition.
• They were really teeing off on me. – off is a particle and on is a preposition.
• We loaded up on Mountain Dew and Doritos. – up is a particle and on is a preposition
• Susan has been sitting in for me. – in is a particle and for is a preposition.The aspect of these types of verbs that unifies them under the single banner phrasal verb is the fact that their meaning cannot be understood based upon the meaning of their parts taken in isolation: the meaning of pick up is distinct from pick; the meaning of hang out is not obviously related to hang.
