You can use two question marks in a sentence and when you use 2 question marks in a sentence it's called an interrogative sentence.
3 question marks is considered rude as using 3 question marks can be interpreted as rudeness and frustration.
Sending a question mark as a single text without a question is considered rude and smug as it makes little sense.
However if you are texting a question or asking what they want or mean then you can use a question mark or text what?
Emojis turn into question marks when your device looks up the image but does not understand it so it shows the question mark instead.
So while the question mark in a box might look like an emoji, it's actually a placeholder or error that means that your device's general software is out-of-date.
On Android, you'll likely see a � (blank rectangle) without a question mark.
Two question marks emoji means that a space was inserted after an emoji at the end of a line.
The question mark was invented by an 8th century clergyman and scholar who name was Alcuin of York.
An upside down question mark is to mark the beginning of interrogative or exclamatory sentences or clauses and it's mirrored at the end with standard punctuation.
The 3 question marks in a box means that the person is using an emoji that's only available in a newer software version.
If you have an Android device, this placeholder character will show up as an empty rectangle.
Having a question mark in a box means someone sent you an emoji your device doesn't support.
When new emojis get created, you typically have to update your device to be able to see them.
The reason people use 3 question marks is when they're attempting to convey an even deeper or more desperate state of uncertainty than a single question mark may convey.
The rules of a question mark are.
You should use a question mark at the end of a direct question.
Do not use a question mark at the end of an indirect question.
You should use an internal question mark to show that something is uncertain.
You can use a comma after question mark when forming multiple questions in a single sentence.
However a question mark should not be used after a sentence other than for multiple questions.
The basic rule when it comes to grammar is to not use a question mark or combine a question mark with periods, exclamation points or commas.
To ask multiple questions in one sentence you put a question mark which is a ? in place of the comma at the end of the sentences.
A set question is a collection of questions that are drawn from a selected tests and pools.
You can use the set questions when you create tests and can choose how many questions you want in the set.
A question can be a statement.
For example if you were to ask someone "Do you know what I mean?" that would be a statement question.
However questions are typically not statements, because they do not express something that is either true or false.
Although sometimes people use them rhetorically to express statements.
An indirect question is a question which is reported to other people in speech or writing, rather than the exact words of the original question, for example '"He asked me what was wrong."
The difference between direct and indirect questions is that direct questions are informal and friendly, whereas indirect questions are polite and formal.
A direct question always ends with a question mark, but this is not always true with indirect questions
Examples of indirect questions and direct questions are.
Has the game started yet?
Are they coming with us?
Can you help me move on Saturday?
Do you know if/whether the game has started yet?
Do you know if/whether they're coming with us?
Is there any chance you could help me move on Saturday?
Notice that the indirect question has the word order "the time is" (i.e., subject + verb) not "is the time" (i.e., verb + subject).
In other words, an indirect question has the same word order as a statement, not a question.) I'm asking where you are going.
Indirect questions are a little more formal and polite.
We use them when talking to a person we don't know very well, or in professional situations, and their form is a little different.
Example of an indirect question: “Could you tell me where the bathroom is?”
