2. Phrasal verbs (I)  In modern English it is very usual to place prepositions or adverbs after certain verbs so as to obtain a variety of meanings: look for = search for, seek look for = search for, seek look out = beware look out = beware look after = take care of look after = take care of  The student need not try to decide whether the combination is verb + preposition or verb + adverb, but consider the expression as a whole. It is also important to learn whether the combination is transitive (i.e. requires an object) or intransitive (i.e. cannot have an object): look for is transitive: I am looking for my passport look for is transitive: I am looking for my passport look out is intransitive: Look out! A car is coming! look out is intransitive: Look out! A car is coming!
