Crasis exercises for 9th grade (with answer sheet)

Choose the alternative in which the use of the accent indicative of crasis is correct.

Answer key explained

We use crasis in adverbial, prepositional and feminine conjunctive phrases. “Sometimes” is a feminine adverbial phrase.

Correction and explanation of the remaining alternatives:

b) The two hours seemed like whole days.

There is no crasis, because in this case “at two o’clock” does not refer to the indication of a time (Class starts at two o’clock.), that is, it refers to counted hours.

c) We will arrive after 10am.

If before the time is indicated there is the preposition "after", we do not use a crasis.

d) He gave the news to João.

We do not use crasis before masculine words, because in this case there cannot be an article junction The with preposition The, after all, we are not talking to João, but rather, João.

The with the preposition The. The phrase indicates that someone usually goes to some exhibitions and not exactly all of them.

If the sentence indicated that someone usually goes to all the exhibitions, it should be “Usually goes to contemporary art exhibitions.”, because in this case, the article is joined The with the preposition The, which corresponds to Usual to go (to + as = to) contemporary art exhibitions.

Answer key explained

I. Night came.

There is no crasis, because the article is not joined The with the preposition The. In this case, there is only an article, because the verb arrive is direct transitive, that is, it does not necessarily need a preposition to complete its meaning.

Meaning of this sentence: The night has arrived. The word “night” is the subject of the sentence.

II. She arrived at night.

We use crasis in adverbial, prepositional and feminine conjunctive phrases. “At night” is a feminine adverbial phrase.

Meaning of this sentence: Someone arrived when it was already night. In this sentence the subject is hidden: (He/she) arrived at night.

This phrase has the meaning of paying for a view, that is, for a landscape.

There is no crasis, because the article is not joined The with the preposition The. In this case, there is only an article, because the verb pay is direct transitive, that is, it does not necessarily need a preposition to complete its meaning.
