Checking transition words and sentence variety
Transition words are the signposts of writing. “However” warns that a contrast is coming, “as a result” links a cause to its effect, “for example” announces evidence. Without them, an essay reads as a list of separate statements; with too many, it sounds mechanical. This checker shows where your text links its ideas, what kinds of links it uses and whether its sentences all start the same way.
Eight kinds of transition
Transitions are grouped by what they do. Addition (furthermore, moreover, in addition) adds a point. Contrast (however, nevertheless, on the other hand) turns the argument. Cause and effect (therefore, consequently, as a result) draws conclusions. Sequence (first, next, finally) orders steps. Example (for example, such as) introduces evidence. Emphasis (indeed, in fact), comparison (similarly, likewise) and conclusion (in conclusion, overall) complete the set. Each group has its own colour and can be switched on and off.
The share of sentences with a transition
The summary shows how many sentences contain at least one transition. Some writing guides and SEO tools suggest that around a quarter to a third of sentences should, and the checker adds a note when fewer than one in five do. Treat the number as a hint: a narrative may flow perfectly well with few transitions, while an argumentative essay usually needs more.
Sentence openers
The second table counts the first word of every sentence. When many sentences start with the same word — “The”, “I”, “This” — the rhythm becomes monotonous. If one word starts more than 30 % of sentences, a warning appears. Varying openers is often as simple as starting with a transition, a time phrase or the object of the sentence.
Avoiding over-signposting
More transitions are not always better. Starting every sentence with “Furthermore” or “Moreover” sounds stiff, and a transition that states the wrong relationship (“therefore” where nothing follows logically) confuses readers. Choose the word that names the real connection, and let some sentences follow naturally.
A worked example
The sample paragraph about bike lanes has eight sentences. Six begin with “The”, so the opener warning appears, and four contain a transition (also, however, therefore, in conclusion). Rewriting two openers — “Within a year, the number of cyclists doubled” and “As a result, car traffic in the centre fell” — varies the rhythm and makes the cause-and-effect chain explicit.
Who uses it
Students check essays and personal statements, teachers give concrete feedback on flow, non-native writers learn which linking words fit which purpose, and content writers improve readability scores.
Revising for flow
Read each paragraph and ask how every sentence relates to the one before it: does it add, contrast, explain or give an example? Where the relationship is not obvious, add the transition that names it. Where three sentences in a row start with a transition, remove one or two; the logic is usually clear without them.
