Common English grammar mistakes: use of “did” and “didn’t”

A deep knowledge and understanding of English grammar may not be essential for basic communication. You can successfully get your messages across in “broken English”; however, if you are serious about improving the quality of communication and being acknowledged for your English proficiency, you should have a strong grasp of grammar and avoid basic grammatical errors.

 

In a recent blog, we covered the common grammar mistakes in the use of 'been' and 'being'. Here, let us address another common and serious issue in the use of “did” and “didn’t”. To do so, let us consider the following conversation between a manager and his colleague regarding a job interview that had been scheduled.

 

Manager: How did the interviews scheduled yesterday go?

Colleague: “No, that guy didn’t came. Of the three other candidates in the list, we didn’t called the guy from Kalyan; of the remaining two, one guy didn’t picked the call and the other guy was not reachable

 

As you read the above sentence, do you get the feeling that something isn’t correct? If you get the slightest sense that it doesn’t sound right, you are actually on the way to improving your English grammar.

 

That’s because there is indeed something fundamentally wrong with the response by the colleague. Look at the words in bold italics:

 

  • didn’t came
  • didn’t called
  • didn’t picked

The mistake lies there. It is not correct to use two past tense words together. When using the word ‘didn’t’, the colleague should have used the present tense of the verbs i.e. come, call, and pick, respectively.

 

So, the grammatically correct response from the colleague to the manager should have been:

 

““No, that guy didn’t come. Of the three other candidates in the list, we didn’t call the guy from Kalyan; of the remaining two, one guy didn’t pick the call and the other guy was not reachable.”

 

While we have given this example with three verbs, this is such a common mistake that you often see it with numerous other verbs.  For example, here are some oft-heard examples of wrong usage of past tense of verbs with ‘didn’t’.

 

  • I didn’t heard the phone.
  • I didn’t knew about the meeting.
  • I didn’t received the e-mail.
  • I didn’t got the cab.

 

The next time you hear of a sentence like that, we hope you will recognise the grammar mistake and avoid it.

Points to remember while avoiding nosy people

Many times, in life, we find people who poke their nose in every matter. They are curious to know everything that happens in our life. Sometimes it becomes difficult to avoid these people as they might be our friend or a close relative. We don’t like to answer each question. So, in today’s blog, we are bringing you some English phrases which will help you avoid answering an unwanted question.

6 phrases to be used

  1. (Sorry) That’s personal

This phrase must be used properly in appropriate situation. When someone asks you too many personal questions that you may not want to answer, you can use this expression.When you are in a group and someone asks you something personal to which you do not wish to answer, just smile, and use this expression.

 

  1. Why do you want to know?

This expression should be used carefully as it sounds a bit rude. If you are in a situation where someone asks something that you feel is none of their business, use this expression. This can be used when you don’t want to share any information.

 

  1. No comment

This is one of the most common expressions used when you don't want to comment on something. Most of the times it is used sarcastically. When there is any sensitive or controversial issue, you can use this expression.

 

  1. Let me get back to you

There are times, when people ask you things that you don't have answers for. Or sometimes, you are unsure whether you should answer the question or not. At that time using this phrase will help you get some time.

 

  1. I would rather not talk about it

Some topics or issues are sensitive, unpleasant, and painful. Like for example, breakups or any other sad news. If someone asks you about your relationship or breakup, then you can say 'I would prefer not talking about such things.'

This phrase is used when you don’t want to answer a particular thing. You can use this phrase and tell someone to wait and watch.

TYPES OF MATRICES

Column Matrix

A matrix is said to be a column matrix if it has only one column.  In general, a = [aij] m x 1 is a column matrix of order m x 1
                      
For example:    
                               
Order of A is 3 x 1 and that of B is 4 x 1

Row Matrix

A matrix is said to be a row matrix if it has only one row.  In general,           B = [bij] 1 x n is a row matrix of order 1 x n

For example: A = [2  0  5  -3]        B = [1/2  0   √3     6    7]
Here order of A is 1 x 4 and that of B is 1 x 5

Square Matrix

A matrix whose numbers of columns are equal to number of rows is said to be a square matrix.  Thus an m x n matrix is said to be a square matrix if m = n and is known as a square matrix of order ‘n’.
                                
For example:    
                                                                  
Hence A is of order 3 and B is of order 2.

Diagonal Matrix

A square matrix B = [bij]mxm is said to be a diagonal matrix if all its non diagonal elements are zero.
                                                         
For example:
                                     

Hence the orders of A, B and C are 1,2 and 3 respectively

Scalar Matrix

A diagonal matrix is said to be a scalar matrix if its diagonal elements are equal.
That is bij = 0, when i ≠ j
           bij = k, when i = j, for some constant k
                                                                  
For example:
Hence the order of A, B and C are 1, 2 and 3 respectively.

Identity Matrix

A square matrix in which elements in the diagonal are all 1 and rest all are zero is called and identity matrix.  In other words, the square matrix A =


Zero Matrix


A matrix is said to be a zero matrix if all its entries are zero.  Another name for zero matrix is null matrix.  It is denoted by 0.
                                       
For example:   
The orders of the above matrices are 1 x 1, 2 x 2 and 2 x 3 respectively.
