Spelling & Dictionary Insight
This English homophone group links 2 distinct headwords, "marquess", "marquis", all sharing a single pronunciation transcribed as //ˈmɑː.kwɪs// in the International Phonetic Alphabet. In our database each homophone row carries the same group_id, which is how the index identifies a phonetically identical cluster regardless of how the letters are arranged. Because the group contains 2members, a reader choosing between them cannot rely on sound alone, only orthography and meaning separate the words on the page.
Dictionary coverage for this set is partial to complete: 2 of 2 members carry a linked Wiktionary definition, and 0 carry a recorded part-of-speech tag. That matters for writers because homophone errors are almost always grammatical substitution errors, the wrong word may be a noun when the sentence wants a verb, or vice versa. When a member lacks a part-of-speech field, it is usually because the form is a proper noun, interjection, or archaic variant that Wiktionary records without full grammatical classification.
Homophone groups are one of the hardest error classes for spell-checkers to catch because every member is a valid English word, the spell-checker sees a correctly spelled token regardless of which homophone the writer chose. Only context, grammar, and meaning can resolve the selection. PlainSpell surfaces homophone groups from IPA pronunciation data drawn from Wiktionary; where IPA is unavailable, a group is inferred from shared rhyme keys rather than phonetic strings. The set above was derived from the former source, which is why each member's pronunciation field is aligned exactly with the group it belongs to.
