Reading method
Phrase cues are not fact or opinion labels
A phrase cue tells you where to look, not what to conclude. Wording alone cannot classify a claim or test its truth.
What the marker actually means
A sentence containing “should” may express a recommendation; a sentence containing “may” may express uncertainty. Neither word proves whether the statement is a fact, opinion, or inference. The tool marks only matching wording in selected passages.
How to use the cue
Read the surrounding paragraph. Identify who is speaking, what evidence is cited, and which limits the author gives. The tool does not evaluate truth, credibility, or intent. If you use the author's exact words, quote and attribute them. If you restate the idea, read the wider source and attribute it as a paraphrase or summary.
The source boundary
Purdue Online Writing Lab distinguishes quotations from paraphrases and summaries. That guidance concerns your use of source material; it does not validate this site's wording heuristic. Read Purdue's explanation, checked 2026-10-05.
