Common grammar mistakes in professional writing
Spot recurring grammar problems in professional writing and use a structured review for agreement, homophones, sentence clarity and punctuation.
Professional writing often fails on simple points rather than obscure grammar: agreement, similar-sounding words, overloaded sentences and unclear punctuation.
A structured review lets you address these risks without turning every email into a grammar exercise.

Agreements that deserve a second look
Subject-verb and adjective agreement become harder to see when several words separate related parts of the sentence. Identify the core structure before checking the ending. If the content contains names, numbers or technical strings, check those separately before keeping the resulting version.
Correctly spelled words in the wrong context
Homophones and valid word forms can still be wrong in a sentence. Review their grammatical role instead of relying on dictionary spelling alone. Check names, numbers and technical strings separately. If the content contains names, numbers or technical strings, check those separately before keeping the resulting version.
Long sentences and ambiguity
A sentence carrying conditions, examples and conclusions at once can become difficult to follow. Split it when separate ideas can stand on their own without losing the relationship. Compare the result with the original before reusing it. Check names, numbers and technical strings separately.
Punctuation as part of the structure
Commas and sentence boundaries affect how ideas connect. Stabilise the sentence first, then refine punctuation rather than polishing signs around a structure that may still change. Compare the result with the original before reusing it. Check names, numbers and technical strings separately.
A practical professional review
Prioritise subjects, headings, opening lines, requests and conclusions, then verify names and figures. Use automated checking as an extra filter rather than the final authority. If the content contains names, numbers or technical strings, check those separately before keeping the resulting version.
