LEXICON
Instead of the word "Dictionary", Lexicon is used when referring to the academic languages, such as Greek, Hebrew, and sometimes Latin. For example, you will rarely find the term "Greek Dictionary", it will instead be called a "Greek Lexicon". The same is true of the other languages.
Where did this word come from?
In the words of Liddell & Scott: The word "lexicon" derives from the Greek word "λεξικόν" (lexicon), neut. of "λεξικός" (lexikos), meaning "of or for words", which comes from "λέξις" (lexis), "speech, word", and that from "λέγω" (lego), "to say", "to speak".
-Henry George Liddell, Robert Scott, An Intermediate Greek-English Lexicon
