- The second mention of the noun is replaced
- Deciding which sentence becomes the main idea vs the description
- Identify the shared noun first
- Identifying the shared link between two sentences
- Replace the second noun with a pronoun like 'who'
- Move the new clause directly after the noun it describes
- The main idea stays as a full sentence
- The effect of relative clauses on writing flow
- The step-by-step process of merging sentences
