Extra Closing Brace
! Extra }, or forgotten $.
What this error means
LaTeX found a closing brace } or $ with no matching opening counterpart. This breaks the internal grouping mechanism that LaTeX uses to scope commands and environments.
Common causes
- Unmatched closing brace from a previous command
- Closed a \begin{...} with } instead of \end{...}
- Forgot to open a group or math mode
- Copy-paste introduced extra braces
How to fix it
Check brace pairing carefully. Every { must have a matching }. Use an editor with brace matching, or add braces systematically and count them. In math mode, every $ must have a closing $.
