Traditional Japanese haiku typically do not use punctuation. However, modern haiku in English may include punctuation for clarity or emphasis.

There is no widely known language that completely lacks punctuation. Punctuation serves important functions in written communication, such as indicating sentence structure and clarifying meaning, so it is a key component of most written languages.

None, open punctuation means there is no punctuation after the salutation or the complimentary close.

A mixed punctuation style typically uses a colon after the salutation.
