English: Linking words

To do writings or essays is useful to start the paragraphs with some words that indicate the purpose. If it is a reason or extra information, or a sumary or a result...

This words make the reading enjoyable. They give a feeling of being fluent and knowing a lot of English. Adjetives make the same effect. When you finish a writing it would be a great idea to review it to add some adjectives and linking words.

In this pages you can find some of this linking words
