When it comes to introducing a contrasting idea or thought, many writers often rely on the phrase "conceding that." However, using the same phrase repeatedly can make your writing sound monotonous and predictable. To avoid this, you may use alternative synonyms that will add variety and interest to your writing. Some of these synonyms include "admitting," "acknowledging," "granting," "accepting," "recognizing," "confirming," and "affirming." Using these synonyms will help make your writing more engaging and better convey your message to the reader. Ultimately, varying your word choice will demonstrate a greater command of the English language and enhance your writing proficiency.
