11AM or 11 AM – Which is Correct?

There’s always been a bit of confusion when it comes to writing time in English. Should it be “11AM” or “11 AM”? We’ve all seen both variations used, but which one is correct? Let’s dive into this topic and shed some light on it.

To start with, both “11AM” and “11 AM” are commonly used in everyday communication, and we can’t really fault anyone for using either. However, if we want to be correct in the strictest sense, we should use “11 AM” – with a space between the numbers and the abbreviation.

The reason for this is that “AM,” in this case, stands for “ante meridiem,” which is Latin for “before noon.” When we write this abbreviation, it is advisable to leave a space between the number and the letters. This follows the general rule in English of leaving a space when using abbreviations that are made up of separate words or parts.

Let’s take a look at a few examples to illustrate this:

1. “I have a dentist appointment at 9AM.”
2. “She always goes for a jog at 6 AM.”
3. “The bus departs at 8:30AM.”

In each of these examples, there is a clear separation between the numbers and “AM,” allowing for better legibility and comprehension. It allows us to distinguish the time from the abbreviation more easily.

However, there are some cases where a strict adherence to this rule might be overlooked. For instance, in informal writing, such as text messages or casual emails, it is common to see “11AM” without a space. This is mainly for convenience and speed, as it saves a keystroke. But do keep in mind that in more formal or professional contexts, sticking to the recommended “11 AM” is preferred.

Furthermore, it’s worth noting that this rule also applies to the use of “PM” (post meridiem) for afternoon and evening hours. For example:

1. “Let’s meet for lunch at 1 PM.”
2. “The concert starts at 7:30 PM.”
3. “After work, we usually go for drinks at 6 PM.”

Again, we see a space after the number and before the abbreviation “PM” to help avoid any confusion.

So, if you want to be technically correct in formal writing or testing situations like the IELTS exam, always remember to use a space between the time and the abbreviation. However, in casual communication, such as text messages, using “11AM” without a space is commonly accepted.

In conclusion, while both “11AM” and “11 AM” are used, it is advisable to stick with “11 AM” for formal settings to ensure clarity and proper adherence to the rules of grammar. And when informality is called for, feel free to go with “11AM.” Ultimately, the choice is yours, but now you have the knowledge to make an informed decision.
