GRAMMAR POINTS TO REMEMBER
When writing formal letters of recommendation, performance reviews, or cover letters, the choice between So and Such dictates how authoritative your praise sounds:
- Creating a “Title” with SUCH:
- To make a lasting impression, package the employee’s value into a noun phrase using Such + a/an + Adjective + Singular Noun. This creates an objective label that sounds highly professional.
- Example: She is such a valuable asset. He is such an inspiring mentor.
- Praising Plural and Uncountable Traits:
- If the trait is plural (standards, skills) or uncountable (leadership, potential), drop the “a/an” and use Such + Adjective + Noun.
- Example: She showed such immense potential. He maintained such high standards.
- Praising Performance and Execution with SO:
- When you want to praise how an employee executed a task, use an adverb and amplify it with So + Adverb.
- Example: She managed the team so efficiently. He mastered the software so quickly.
- Emphasizing Quantities:
- If you are highlighting a positive lack of something (like mistakes) or an abundance of something (like value), remember that many, much, few, and little always take SO, never “such”.
- Example: She made so few errors. He added so much value.
