Cohesion & Topic Chaining
Linking sentence to sentence
Make each sentence's subject connect back to the previous sentence for a smooth thread.
Definition & mechanics
Cohesion comes from consistent, linked subjects. When each sentence's topic picks up a thread from the one before—by repeating a key term or referring to it clearly—the reader follows a single chain of thought. Erratic, shifting subjects force the reader to reorient at every sentence.
A curiosity
Cohesion and coherence differ: cohesion is the sentence-to-sentence glue, coherence is the whole document's sense of direction. You can have local glue and still be globally lost—but you rarely feel coherent without the glue.
Example
Before (topics jump)The cache stores recent results. Latency is reduced this way. A TTL governs each entry. Eviction happens when memory is low.
After (chained)The cache stores recent results, which reduces latency. Each cached entry has a TTL, and the cache evicts entries when memory runs low.

Copyable Prompt
Apply the concept of Topic Chaining (strengthen cohesion by keeping sentence subjects consistent and linked—begin each sentence with a topic that connects to the previous sentence, repeat key terms rather than swapping in vague synonyms, and avoid abrupt shifts in subject) to the provided text and rewrite in place. Apply the edits directly to the file as a clean, production-ready deliverable. Output ONLY the revised document text without embedding revision notes, changelogs, or meta-commentary in the file itself—put any explanations in your chat response only.
