:: A preposition links nouns, pronouns and phrases to other words in a sentence.
:: The word or phrase that the preposition introduces is called the object of the preposition.
Prepositions are simple words but they are not as easy to use as they appear to be. If used wrongly, they become adverbs and conjunctions and convey different meanings as the following examples show:
a) It was a kite that we looked above us. (adverb)
b) I noticed an air plane above the cloud. (preposition)
c) They waited outside the cinema for him. (adverb)
d) The sheep are outside the fence. (preposition)
e) We entered after her. (adverb)
f) He arrived after we had left. (conjunction)
g) I go jogging every day after work. (preposition)
~ A phrasal verb is a verb that is combined with a preposition (at, on, over, etc.) or adverb (back, down, off, etc.), and together has its own special meaning.
– Get away means escape
~ Speak up means speak louder
2. Phrasal Verbs (Separable)
:: The nouns come between the verbs and the participles, and the noun objects come after the participles of the phrasal verbs.
~ His part-time office job is to put the files away. (The noun files is between verb put and the participle away.)
~ They called off the match due to bad weather. (Noun object match comes after the participle off.)
Phrasal Verbs (Non-Separable)
~ He will look after my dog while I am away.
(INCORRECT: He will look my dog after while I am away.)
~ They called on her when she was hospitalized.
(call on = pay a brief visit. INCORRECT: … called her on…)
