1. Replace what follows article “a” with a masculine term. If you need "ao", the phrase has a backstroke.
Examples:
- I'll go to school? --> I'm going to college.
- Call the doctor. --> Call the doctor.
- Met the neighbor. --> Met the neighbor.
2. Remember these rhymes: I'm going to, I'm back. Crasis there! I go to, come back from. Crasis for what?
Replace the verb "go" with the verb "come back". If you need to complete it with "da", the sentence has a backquote, but if you need to complete it with "de", the sentence has no backquote.
Examples:
- I'm going to Italy. --> I come back from Italy.
- I'm going to Portugal. --> I come back from Portugal.
- I'm going to Bahia. --> I return from Bahia.
3. In the time indication, there is a crasis. In the counting of hours, no!
Examples:
- I arrive at 2am.
- The two hours of the film flew by.
- Class starts at 3pm.
4. Memorize: Whether in the afternoon or in the evening, use the backline in front of feminine expressions.
Examples:
- said everything openly.
- live at odds.
- Turn on the right.
2 cases where we don't use backquote
1. We do not use a back-quote before verbs and repeated expressions.
Examples:
- Started walking yesterday.
- We need to talk face to face.
- Possession to fill the bottle dropwise.
2. We do not use a crasis before an "a" that is accompanied by a plural feminine word.
Examples:
- I mean the students of the night shift.
- the way is to go to stores of antiques to try to find the object.
- I prefer fish the meat red.
What is crasis?
Crase is the combination of two letters a: one preposition to ordinary article to (or with the pronouns Thethat, Thethat, Thekilo, The which).
When we need to use them together, we put a mark on a. This mark is the grave accent (`), which looks like this: à, that, that, that, to which.
Examples:
- how about going à Beach tomorrow?
- refers that one client?
- maybe go that one store.
- we prefer this that one.
- The school which I mean, stay there.
Check out the step-by-step explanation of each of the examples:
How about going to the beach tomorrow?
- The verb to go needs a preposition to complete its meaning (Go somewhere.), so this sentence has a preposition (How about going to???).
- The word beach accepts the article before it (the beach).
- So, the sentence above combines a preposition to ordinary article to (go to the beach).
Are you referring to that customer?
- The verb form to refer needs a preposition to complete its meaning (Refer to something.), therefore, this sentence has a preposition to (Refers to...).
- The word that starts with a.
- So, we use the backtape to not repeat the preposition to and the letter a of that one, that is, we use that one instead of that one (Refers to that one).
Maybe go to that store.
- The verb ir, in the form Vá, needs a preposition to complete its meaning (Maybe it goes somewhere.), so this sentence has a preposition (Maybe it goes to...).
- The word that starts with a.
- So, we use the backtape to not repeat the preposition to and the letter a of that one, that is, we use that one instead of that one (Maybe go to that one...).
We prefer this to that.
- In this example, we are comparing our preference. (I compare this to...). We need the preposition a to complete the sense of the sentence.
- The word that starts with a.
- So, we use the backtape to not repeat the preposition to and the letter a of that, that is, we use to that instead of to that (I compare this to that).
The school I'm referring to is there.
- The verb form "I mean or I refer" needs a preposition to complete its meaning (I mean something.), therefore, this sentence has a preposition (I mean...).
- The word which is related to the word school.
- The word school accepts the article a before it (the school).
- So, the sentence above combines a preposition to ordinary article to (I mean school.)
