Transition words have important roles as "bridges" to guide the reader through the text and ideas when you write persuasive text. Especially in analysis (and argument) transition terms often serve as the glue to hold your description of evidence (the "what") or the process under which a situation or action occurred (the "how") to your thesis (the "why").

Compare the writing A) with the writing B) that includes transitional signals.

A) Nothing is known about Adrian´s birth. We know that, during his early years, he was raised by hedgehogs in Birmingham, England. This upbringing would have a lasting effect on him. Adrian is a nocturnal creature who has been known to curl himself into a ball on occasion. The diet on which Adrian likely subsisted when he was young, namely insects, left him with a phobia for anything with more than four legs. Adrian was able to lead a relatively normal life. Mr. and Mrs. Smith rescued him from the Birmingham hedgehogs. The Smiths set about teaching Adrian how to behave in the world of humans. They taught him to speak English. They taught him to read. They sent him to school for the Arts. Adrian quickly became a talented guitar player. He decided that if he could not be a professional musician, he would curl himself into a ball forever. Adrian met some fellow musicians who were as talented as he. They formed a band that became a huge success.

B) It is true that nothing is known about Adrian´s birth, but we know that, during his early years, he was raised by hedgehogs in Birmingham, England. This upbringing would have a lasting effect on him; for example, Adrian is a nocturnal creature who has been known to curl himself into a ball on occasion. In addition, the diet on which Adrian likely subsisted when he was young, namely insects, left him with a phobia for anything with more than four legs. Nevertheless, Adrian was able to lead a relatively normal life after Mr. and Mrs Smith rescued him from the Birmingham hedgehogs. The Smiths set about teaching Adrian how to behave in the world of humans. First, they taught him to speak English. Second, they taught him to read. Finally, they sent him to a school for the Arts. As a result, Adrian quickly became a talented guitar player, and he decided that if he could not be a professional musician, he would curl himself into a ball forever. Ultimately, Adrian met some fellow musicians who, in comparison, were as talented as he, and they soon formed a band that became a huge success.
