English Confusable Pairs

Spelling & Dictionary Insight

The English confusables index tracks 529,999 word pairs in total, alongside 545,755 headword entries and 2,182 homophone records. The current view , the A–Z directory filtered to the letter "M", returns 16,727 pairs whose first word starts with that letter. Across the visible 168 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 and sortable; 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 English 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 "made-vs-mara", 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.
