How to Say Appendix in Spanish
Apéndice · noun · ah-PEHN-dee-seh
The word 'apéndice' covers both the anatomical organ (the vermiform appendix in the lower right abdomen) and supplementary sections in documents. For document appendices, 'anexo' is also commonly used, particularly in academic and legal writing.
Pronounced ah-PEHN-dee-seh with stress on the second syllable. The accent mark on the 'e' is mandatory as this is an esdrújula word.
Tuvieron que operarme de urgencia porque se me inflamó el apéndice.
They had to operate on me urgently because my appendix became inflamed.
