Portuguese Confusable Pairs

Spelling & Dictionary Insight

The Portuguese confusables index tracks 75,631 word pairs in total, alongside 39,583 headword entries and 78 homophone records. The current view , the A–Z directory filtered to the letter "R", returns 2,413 pairs whose first word starts with that letter. Across the visible 25 pages, each row links to a side-by-side comparison page.

On this page, 0 of 100 pairs carry a stored explanation string, a short editor-written or data-derived note that states the distinction in plain language. The rest rely on the side-by-side definition table on their detail page to do the work. Pairs without an explanation are still fully indexed: their word1/word2/slug/confusion_score fields are populated, which is what lets the ranking sort work; the absence is purely in the narrative layer.

Confusable pairs are the class of spelling error that no automated spell-checker can catch, because every member of every pair is already a valid Portuguese dictionary word. Substitution errors (their/there, affect/effect, quiet/quite) survive every automated pass. PlainSpell's approach is to index the pair directly, word1, word2, a shared slug like "rimar-vs-rolar", and the distinguishing fields, so readers can look up the comparison before they publish. The A–Z directory exists so readers who remember only one half of a pair can still reach the comparison page from its first letter.
