Expert writing Tips

Best practice

Avoid using the phrase "you must so" in formal writing. Instead, opt for clearer and grammatically correct alternatives such as "therefore you must" or "you must therefore" to ensure your message is easily understood.

Common error

Ensure adverbs like 'so', 'therefore', and 'thus' are correctly positioned in your sentences. Placing them between 'must' and the verb can create awkward and grammatically incorrect phrasing. Instead, place the adverb before 'must' or after the main verb.
