What is a sentence? part 2

Last time we saw that a statement sentence has to have a subject and a verb. 

In commands such as "listen", the subject is always "you" but it is not stated, so commands are sentences.   

In these days of text messages and tweets and comments we often don't use sentences which is fine in the context. But the point of this blog is how to write correct English when it is important eg for work, for essays, for reports, for job applications and so on.

Going to get some work done.  This is not a sentence. It should be "I'm going …"

Get your coat.  This is a sentence. It is a command.
How to stay safe by the sea. This has no subject/verb and is not a sentence. It is typical of a headline or byline.
