A transition is the connection between one idea and the next — the move that links sentences within a paragraph, paragraphs within a section, or sections within a text. Transitions make the relationship between ideas explicit so the reader can follow the argument without getting lost.
Transitions work through three mechanisms:
- Logical connectors — words and phrases that signal relationships: “however” (contrast), “therefore” (consequence), “for example” (illustration), “similarly” (comparison), “first… second… third” (enumeration). These are the most visible transitions but not always the most effective — overuse makes prose feel mechanical.
- Repetition of key terms — repeating a word or phrase from the previous sentence or paragraph carries the reader’s attention forward. Joseph Williams called this the “topic string”: a sequence of sentences that begin with the same topic, creating cohesion through repetition [@williams2006].
- Old-before-new information — each sentence opens with something the reader already knows and ends with something new. This known-to-new pattern is the deepest form of transition: it makes each sentence feel like a natural continuation of the last.
Bad transitions announce themselves: “In this section, I will discuss…” Good transitions are invisible — the reader moves from one idea to the next without noticing the seam. The test is whether you can remove the transitional word and the connection still holds; if it does, the connection was structural, not cosmetic.
