Welcome to the Dictionaries page. Just as there are general dictionaries on the Internet, so there are specialist ones as well - similar to my Encyclopedias Page.
When I first started this section of my site I though it would be an easy task. Instead I found literally hundreds of on-line dictionary resources. I have intentionally left out translation dictionaries except American-English / English-American (although I may address this issue at a later time) but have included the odd thesaurus and glossary or two.
It is sometimes a very thin line between a dictionary and an encyclopedia. Often what is termed a dictionary should really be an encyclopedia, and vice versa. I have adhered to the descriptions given for the sites on the Internet even though I may sometimes disagree with them.
For your information, the Cambridge dictionary gives the following definitions:
Dictionary:
1 a book
that contains a list of words in alphabetical order with their meanings
explained or written in another language, or a similar product for use
on a computer:
a French-English/English-French dictionary
a bilingual/monolingual dictionary
To check how a word is spelt, look it up in a dictionary.
2
a book which gives information about a
particular subject, in which the entries are given in alphabetical
order:
a biographical/science dictionary
a dictionary of quotations.
Encyclopedia:
1 a book or set
of books containing many articles arranged in alphabetical order which
deal either with the whole of human knowledge or with a particular part
of it:
The Cambridge Encyclopedia of Language
I think that you'll agree that the second definition for Dictionary seems very close to the latter part of the definition for Encyclopedia.
WARNING
You will find medical dictionaries listed here. Never rely simply on your own diagnosis of an illness or disease. Always consult a qualified medical practitioner.
