<em>''For example''</em> - primarily used for example making. Not typically used for cohesive sentence transitioning.
<em>''Moreover''</em> - a rarely used transition word. Typically used to proceed a sentence into another paragraph usually of a different topic. Less cohesive due to generalization and various usage.
<em>''Furthermore''</em>- creates a seamless transition from topic A due to the word ''further'' which enunciates the extending of topic A into another sentence.
