What authors say 

What they mean 



This is an analogue of 

I have to have some excuse for publishing it 
This is of interest in applications 

I have to have some excuse for publishing it 
The proof is now complete 

I can't finish it 
I cannot follow the details of X's proof 

It's wrong 
We omit the details of this calculation 

I can't do it 
This problem is difficult 

I don't know the answer 
Without loss of generality 

I have done an easy special case 
To fix the ideas 

To consider the only case I can do 
X's proof is ingenious 

I understand it 
It may be of interest 

I have to have some excuse for publishing it 
X's paper is interesting 

I don't understand it 
This is a known result but I reproduce the proof for the convenience of the reader 

My paper isn't long enough 
Par abus de langage 

In the terminology used by other authors 
It is natural to begin with the following considerations 

We have to start somewhere 
This was proved by X but the following new proof may present some points of interest 

I can't understand X 
To simplify the notation 

It is too much trouble to change now 
It will be observed that 

I hope you have not noticed that 
It is obvious 

I can't prove it 
The details may be left to the reader 

I can't do it 
I wish to thank the referee for his suggestions 

I loused it up 
By a straightforward computation 

I lost my notes 
This problem is trivial 

I know the answer 
This result is well known 

I can't find the reference 



Exercises for students: 





I am indebted to Professor X for stimulating discussions 


However, as we have seen 


In general 


It is easily shown
