Linking ideas

You can use linking words to join different ideas together. Using linking words makes the presentation of your ideas more interesting and easier to understand. They have a number of different functions:

Addition: also, and, in addition, too
Cause and effect: as a result, because, so
Condition: if, unless
Contrast: although, but, however, though

You can use many of these linkers either at the start or the middle of sentences:
Only at the end of a sentence: too
In the beginning or in the middle of the sentence: also, and, because, so, if, unless, although, but
In the biginning, middle or the end of a sentence: though.
