Key Takeaways
- Transition phrases don't earn points directly — they signal to the grader which reasoning skill you're using, sentence by sentence.
- A phrase bank below covers all 6 reasoning skills: causation, comparison, CCOT, contextualization, complexity, and corroboration.
- A worked example shows the same paragraph with generic vs. skill-specific transitions.
Why It Matters
The Missing Piece: Words, Not Just Concepts
The Historical Thinking Skills glossary explains what causation, comparison, and complexity actually mean. What it doesn't give you is the sentence-level language to signal you're using them in real time, under a 40-minute clock.
No rubric row scores vocabulary directly. But an AP reader moves through hundreds of essays quickly, scanning for evidence of each skill. A sentence that opens with "this directly caused" is instantly legible as causation; a sentence that just narrates events makes the reader work to find the reasoning you intended. The phrases below aren't decoration -- they're how you make your reasoning skill visible on the page.
The Phrase Bank, by Reasoning Skill
Organized to match the Historical Thinking Skills glossary. Pick 2-3 phrases per skill to actually memorize -- you don't need all of them.
| Skill | Transition Phrases |
|---|---|
| Causation | "This directly caused..." · "As a direct result of..." · "This set in motion..." · "The primary driver of [X] was..." · "This, in turn, led to..." |
| Comparison | "While [A] emphasized..., [B] instead..." · "Both [A] and [B] shared..., yet they diverged in..." · "In contrast to..." · "This mirrors [X], but differs in that..." |
| Continuity & Change (CCOT) | "Despite this change,... remained constant" · "This marked a break from..." · "Building on this earlier pattern..." · "Even as [X] shifted,... persisted" |
| Contextualization | "In the broader context of..." · "This took place against a backdrop of..." · "Building on decades of..." · "This did not occur in isolation; it followed..." |
| Complexity / Synthesis | "This same tension resurfaced decades later when..." · "A similar pattern is visible in [different period/place]..." · "Even today, this debate echoes in..." · "This complicates a simple narrative of... because..." |
| Corroboration | "This account is reinforced by..." · "Read together, Documents X and Y suggest..." · "This aligns with the perspective in Document X, which..." · "Taken together, these sources show..." |
Worked Example
Same Content, Different Transitions
Both versions below make the same historical point. Only the transition phrasing changes -- but one signals causation clearly, and one leaves the reader to infer it.
Generic (reasoning skill unclear)
"The stock market crashed in 1929. Many banks failed. Unemployment rose sharply in the following years."
Signals causation clearly
"The 1929 stock market crash directly caused a wave of bank failures, which in turn drove unemployment sharply upward in the years that followed."
The historical content is identical. The second version names the causal chain explicitly instead of listing events in sequence and hoping the reader infers cause and effect. See the Thesis Formula guide for how this same principle applies to your opening claim.
Where This Fits in Your Score
These phrases support the Analysis & Reasoning row on the DBQ Rubric and LEQ Rubric, and the synthesis-based complexity point covered in 8 Themes & the Complexity Point. Once you've drafted a practice essay, use the self-grading checklist to check whether your reasoning actually comes through on the page.
Frequently Asked Questions
Do transition words actually earn points on the APUSH DBQ or LEQ?
Not by themselves -- no rubric row scores vocabulary. What they do is signal to the reader, sentence by sentence, which reasoning skill you're using. A grader scanning quickly for causation, comparison, or complexity finds it faster -- and is less likely to miss it -- when your own phrasing names the skill instead of making them infer it from the content alone.
Can I just reuse the same transition phrase throughout my essay?
You can reuse a phrase within one paragraph without penalty, but varying it across paragraphs reads as more controlled writing and keeps the argument from feeling mechanical. More importantly, if your prompt shifts between reasoning skills, your transitions should shift with it.
Are these the same transition words used in regular English essays?
Some overlap, but APUSH-specific phrasing is more useful because it ties directly to the historical reasoning skill the rubric names -- generic transitions like "furthermore" or "in addition" don't signal causation, comparison, or complexity the way a phrase built around those specific skills does.
A Note on This Page
These phrases are teaching tools, not a checklist a grader looks for -- what earns points is the reasoning itself, demonstrated through evidence and analysis. Always confirm current rubric language on AP Central.
