Yes, in American English, the abbreviation "Mr." typically includes a period at the end.
Explanation:
In American English, it's standard practice to use periods after abbreviations like "Mr.," "Mrs.," "Dr.," and "Ms." This convention signifies that the word has been shortened. The presence of the period helps distinguish the abbreviation from a complete word.
Example:
- "Mr. Smith will be arriving shortly."
Exceptions
While less common, British English often omits the period after "Mr," "Mrs," and "Dr" as these are considered truncated words (where the ending of the word has been cut off) rather than abbreviations (where letters from the middle have been removed). However, American English always includes the period.
