Punctuation
Full stops, question marks, exclamation marks
Match the end mark to the sentence type; do not stack multiple marks.
Why this happens
End marks — full stops, question marks, exclamation points — close sentences and set tone. Writers use question marks on indirect questions (*He asked why was she late?), drop periods in formal paragraphs, or stack exclamation marks in academic work. Each mark signals how the reader should interpret the clause. A quick final scan for mark type catches errors that spellcheck will never flag.
