Dictionary.com Word FAQs
Where can I find out the meaning of the symbols in a dictionary, like the dagger (†) or parallels (||)?
It is very important to read the Explanatory Notes or Guide to the dictionary, which is where most of the symbols will be explained. Symbols are used within definitions, etymologies, and other features of dictionary entries. Pronunciation symbols will be described in the Guide to Pronunciation (or Pronunciation Guide). A list of abbreviations for the book might include the symbols used. Do remember that different dictionaries use different symbols. It is important to find out what the specific dictionary has designated the symbols to mean.
