Punctuation in the English language helps the reader to understand a sentence through visual means other than just the letters of the alphabet.[1] English punctuation has two complementary aspects: phonological punctuation, linked to how the sentence can be read aloud, particularly to pausing;[2] and grammatical punctuation, linked to the structure of the sentence.[3] In popular discussion of language, incorrect punctuation is often seen as an indication of lack of education and of a decline of standards.[4]
