Subtle Transitions Within and Between Paragraphs (ORG 601)

A transition between two sentences only has to bridge a few words of meaning. A transition between two paragraphs has to bridge two whole arguments, and that's a bigger job. Think of each paragraph as a claim in a box. The question is never "what word fits here" in isolation — it's "what is the arrow between Box 1 and Box 2 actually doing?" Does paragraph 2 agree with paragraph 1, add to it, or push back against it? The opening sentence of paragraph 2 has to state that relationship honestly before it can transition.

This is why the last sentence of the previous paragraph is a trap. A paragraph often ends on a detail, an example, or a stray fact that isn't its main point — the mules towing barges, say, at the end of a paragraph about a canal saving a town. If you build your transition off that last sentence, you'll answer the wrong thing. You have to step back, find the paragraph's actual claim, and write an opener that responds to that claim. A good test: cover up everything except the last sentence of paragraph 1 and the first sentence of paragraph 2. If the logic only works because of a coincidental word overlap, it's broken.

This connects directly to the two-boxes-and-an-arrow idea for transitions generally. The arrow has a real direction — same-direction (addition, continuation), or opposite-direction (contrast, concession) — and your job is to discover which one it is from the content, then choose words that match. Between paragraphs, this gets subtler because both boxes are bigger and the real point can hide anywhere inside them, not just at the seam.
