Appendices are placed at the end of a document and are labeled with letters or numbers (e.g., Appendix A, Appendix 1).
Word Origin
From Latin 'appendix' meaning 'something appended', from 'appendere' (to hang upon), from 'ad-' (to) + 'pendere' (to hang).
Usage Notes
In academic writing, 'appendix' is often pluralized as 'appendices' (following Latin) or 'appendixes' (following English). 'Appendix' as a body part is always singular.
