In a standard dictionary, where can you find the key to pronunciation marks?

A. In the front of the dictionary

B. At the bottom of each page

C. In an appendix

D. Within the definitions

The presentation depends from one dictionary to another. In one case, the Concise Oxford English Dictionary, or the Chambers 21st Century Dictionary, the pronunciation keys are found along the bottom of each page. These are like footnotes of the page.
