When choosing a online dictionary, you want one that's fast loading, not many ads, not cluttered, has human voice recording (as opposed to machine pronounced) for many imported words (Bach, fete, sui generis, …), but most of all, contains the definition from a dictionary you like.
Review of Dictionaries
I highly recommend American Heritage Dictionary. Its vocabulary size is larger than all the others online. Its definition is professional and rich. It is not dumbed-down “explanatory” style as in learner's dictionaries, nor is it terse and incomprehensible as in the abridged “Merriem-Webster collegiate”, nor is it “web samples” as in Word Net.
The worst is the Merriem-Webster COLLEGIATE dictionary. It is a abridged dictionary and very popular due to aggressive marketing.
Also, extremely bad is the dictionary bundled with every Mac OS X: New Oxford American Dictionary. It is a “learner's dictionary” and a bad one.
What's Learner's Dictionary?
“Learner's dictionary” is a class of dictionaries that take a explanatory approach. Instead of giving a definition, it simply explains what the word means. This is great if you are a casual reader and simply want to know a word's meaning quickly, but it has several serious problems.
- You won't be able to understand a word unless it is used in the most common way. Because, learner's dictionary usually omits a word's less popular meanings.
- It does not give you any sense at all of the word's connotation, background, etymology. If you are reading a old classic English novel (e.g. Jonathan Swift), or finely-crafted journalism such as Time Magazine articles, learner's dictionary will puzzle and mislead you.
