Phrasal verbs are a combination of a verb and one or more particles, which are usually prepositions or adverbs. These particles change the meaning of the verb, often creating a new meaning that is different from the original verb.
Here are some examples of phrasal verbs:
* Look up (meaning to search for information)
* Turn on (meaning to start something)
* Give up (meaning to stop trying)
* Put off (meaning to delay something)
It's important to note that phrasal verbs can be tricky because they often have idiomatic meanings. This means the meaning of the phrasal verb is not easily deduced from the individual meanings of the verb and the particles.
