Question

What is the correct way to punctuate MD (short for medical doctor)?

Answer 1

Hint: Doctor of Medicine is a medical degree that has various meanings depending on the jurisdiction. MD: The Latin title Medicinae Doctor, or Doctor of Medicine, is abbreviated as MD.
Punctuation refers to the use of spacing, traditional signs, and some typographical devices to help in the comprehension and proper reading of written text, whether read silently or aloud.

Complete answer:
An abbreviation is a word or expression that has been simplified in some way. It may be a string of letters or a selection of words from the complete version of the word or expression. M.D. is an abbreviation for Medical Doctor.

The M.D. is a specialised graduate degree in the United States and several other countries. This emerged in part because many medical professionals in the 18th century received their training in Scotland, which used the M.D. degree nomenclature. Bachelor of Medicine, Bachelor of Surgery was used in England, and it gradually became the practise in Scotland in the 19th century.

Punctuation rules change with language, place, register, and time, and they're still changing. Certain aspects of punctuation, such as those used in online chat and text messages, are stylistic and therefore the author's preference, or tachygraphic language forms.

The correct way to punctuate MD (Medical Doctor) is M.D.

Note: In English, there are two main punctuation styles: British and American. They mostly differ in how they treat quotation marks, particularly when combined with other punctuation marks. Punctuation marks such as periods and commas are only put within the quotation mark if they are part of the quoted text, and they are placed outside the closing quotation mark if they are part of the containing sentence in British English. However, in American English, such punctuation is almost always put within the closing quotation mark.
