Incorrect spelling, explanation: using the forms am and pm when talking about time in English is rather easy. Nevertheless, there is one thing to remember and it refers to spelling. A common mistake is to spell the time as e.g. 10am – without the space – while the correct spelling is with the space left, which is 10 am.
Correct spelling, explanation: a 24-hour day in English is divided into two parts and is expressed by the forms am and pm. Both of them come from Latin and, more precisely, am stands for ante meridiem (before noon) and pm is post meridiem (after midday) Therefore, for instance, 10 am will be used in the morning while 10 pm in the evening. You can also spell 10 am as 10 a.m. or 10 AM.
Definition of 10 am:

We have gotten sloppy when writing time abbreviations. 10 am and 10:00 am are both incorrect. The abbreviations for “ante meridiem” and “post meridiem” (before noon and after noon) are either AM/PM or a.m./p.m. Hence, 10 a.m. and 10:00 a.m. are correct.
Is 10 a.m. incorrect?
