You add a transition phrase, then another, but the paragraph still feels crowded. The difficulty may not be a missing connective. Two different pieces of work may be competing for the same space.
A paragraph break gives the reader a chance to recognise a new step. It is a structural choice, not merely a way to make the page look less dense.
Label what the paragraph is doing
Write a short note beside it: introduces the problem, explains the example, considers an objection, or shows a consequence. If your label needs several unrelated clauses, examine whether there is more than one main focus.
Purdue OWL’s paragraph guidance emphasises unity and the value of giving new points their own space. That principle is more useful than demanding the same number of sentences in every paragraph.
Look for a genuine change of direction
In an invented article about a shared garden, one paragraph might explain how tools are stored. The next might examine why newcomers struggle to find them. The subject remains the garden, but the work changes from describing a system to identifying a problem.
Place the break where that shift begins. Then ask whether the first sentence of the new paragraph gives enough connection to what came before.
Do not strand the evidence
A very short paragraph can create emphasis, but separating every sentence may leave examples detached from the claims they support. Keep the explanation close enough that a reader can see why the detail is there.
Try reading only the first sentence of each paragraph. Does the route make sense? This is a quick diagnostic, not proof that every paragraph must open with a formal topic sentence.
Use the break, then reassess the link
Once the two ideas have their own space, you may discover that the repeated transition phrases are no longer needed. If the connection still feels weak, explain the relationship itself: cause, contrast, example or consequence. The reverse outline lets you test those relationships across the whole piece.
