Linking words and phrases connect opinions, reasons, and ideas in a text. These are called transitions. Some sentences also serve as transitions between paragraphs and ideas.
Linking words and phrases are used to connect opinions (what the author thinks or feels about something) with evidence that explains the opinions. Some linking words compare ideas or show time and the order in which events happen.
Here are some examples of linking words:
Connect opinions and evidence - consequently, specifically, in contrast
Connect ideas - also, another, and, more
Show time and order of events - first, next, finally, then
