Types of sentence
A sentence is a unit of grammar. Typically, in writing, it begins with a capital letter and ends with a full stop.
Sentence structures
There are three types of sentence structures: simple, compound and complex.
Simple sentences
Simple sentences have only one main clause:

Compound sentences
Compound sentences have two or more main clauses, joined by a coordinating conjunction:
I phoned her but she wasn’t there.
Are you coming or are you staying at home or will you go and see Mum?
Complex sentences
Complex sentences have a main clause and one or more subordinate clauses, introduced by a subordinating conjunction (The main clause is in bold; the subordinate clause is underlined.):
You can call me if you have any problems.
I got up earlier than usual because I had to get the 6.30 train.
