In everyday writing and professional communication, small grammar choices can make a big difference. One common point of confusion for writers, students, and professionals alike is the usage of “in regard” versus “in regards.” At first glance, both expressions may seem correct, and you might even see them used interchangeably in emails, articles, and formal documents. However, when it comes to correct grammar, only one of these phrases is traditionally accepted in standard English usage. Understanding the difference is essential for maintaining clear communication, especially in formal writing, business correspondence, and academic contexts.
The phrase “in regard to” has long been recognized as grammatically correct, while “in regards to” is often considered an informal expression or a common grammar mistake. This confusion usually arises because the word “regards” is frequently used correctly in other contexts, such as sending regards or kind regards in letters. As a result, many writers mistakenly assume the plural form also works in this phrase.
Quick Answer: In Regard vs In Regards
For a straightforward answer: “In regard” is correct in formal writing, while “in regards” is often used informally but considered less standard.
- In regard: Singular, precise, formal. Example: “In regard to your recent inquiry, we have updated our policies.”
- In regards: Plural, informal, often seen in casual emails or messages. Example: “In regards to your last email, I’ll get back to you tomorrow.”
Think of it this way: “in regard” is your safe choice for professional communication, while “in regards” is more conversational, though not technically correct in formal English.
The Origin and Evolution of “In Regard” and “In Regards”
Understanding the history of these phrases helps explain why the singular form dominates formal writing.
- “In regard” dates back to the 16th century. It originally appeared in legal and formal documents, emphasizing reference or consideration. The singular form aligns with the Latin root regardare, meaning “to look at” or “to pay attention to.”
- “In regards” emerged later as a pluralized version, likely influenced by the common phrase “best regards”, which is used in letter closings. Over time, this plural form began appearing in casual communication, but it never gained formal acceptance.
Interesting fact: Early English legal documents strictly used “in regard”, which shows how rooted this usage is in formal contexts.
British English vs American English Differences
Regional variations can also impact which phrase you use.
- American English: Tends to prefer “in regard” in both professional and casual writing. “In regards” is often tolerated in informal emails but is still marked as incorrect in style guides like The Chicago Manual of Style.
- British English: Some writers occasionally use “in regards” in informal correspondence, but like American English, the singular “in regard” is standard in formal writing.
Key takeaway: Regardless of region, consistency matters. Avoid mixing singular and plural forms in the same document to maintain professionalism.
