Right in the wiki for this sub , I've linked a bunch of free online dictionaries. For beginner and intermediate learners, I'd say it's good to stick with a "learner's dictionary," which is a dictionary designed specifically for use by non-native speakers. It has fewer words than a standard dictionary, but it will focus on the most common definitions of words, and provide more usage notes. The ones specifically mentioned in the wiki are Oxford Advanced Learner's Dictionary Cambridge Learner's Dictionary Longman Dictionary of Contemporary English Collins COBUILD Britannica Dictionary (formerly Merriam-Webster Learner's Dictionary) Answer from corneliusvancornell on reddit.com

r/literature on Reddit: What is your primary dictionary?
December 21, 2023 -

I know most people just look words up on their phones but I like to use the old school dictionaries. I record all the words I look up while reading a book and then review them to better assimilate them. I’ve used the New Webster’s Unabridged for ages as my primary dictionary. I have serveral others (Oxford American, Merriam Webster) I keep on the shelf but I always go back to the New Webster’s even though it’s like lifting a care tire. I find some really interesting subtle differences in definitions that are particularly pertinent to literary language. What do you use and why?

There is no single best or most complete or most authoritative dictionary or dictionary website, and it's best if you don't rely on just one, because dictionaries have different purposes or philosophies and will differ in how they present senses or nuances. Also, general purpose dictionaries are aimed at native speakers, and may provide definitions that seem circular or overly complex to a learner. To that point, I recommend using OneLook , which links you directly to entries from several different dictionary websites. For learners, I recommend Oxford OALD , Macmillan , Cambridge CALD , Longman , or Merriam-Webster MWLD (especially for American usage). Collins COBUILD is also popular, but I personally don't like the way they present the material. The Cambridge Dictionary and Collins Dictionary websites can be useful because they search multiple dictionaries at once, although in my experience (including on this sub), this has served to confuse learners as much as it helps them. For general purpose dictionaries, Lexico (formerly Oxford Living Dictionaries) and Cambridge are reliable for British uses and Merriam-Webster and the American Heritage Dictionary for American uses. AHD is more linguistically conservative than MW. If you are dealing with historical texts and want something truly comprehensive, the most authoritative resource is the Oxford English Dictionary (not just any English dictionary published by Oxford, but the work known as the OED). This is a historical dictionary that attempts to catalog all meanings that all words have ever had since the dawn of the English language itself, including senses that may not have been used in hundreds of years. It is structured very, very differently from general purpose dictionaries and not intended for everyday use, but it is fascinating to read through some of the entries.

r/books on Reddit: What is your favourite dictionary and why?
June 5, 2021 -

I was just thinking about how I got interested in words. It was when I discovered at my parents house a big red New World Dictionary. It was a hardcover book easily the size of my 7-year old torso that I could carry around like an oversized luggage and place on various beds and tables as I read it. I would spend hours reading it. No, really. Like a book. It seemed like a choose your own adventure game. It had a lexicographer guide and it showed root word relations. I would read one word and discover an antecedent word or related root and go look that up. That’s when I first got this idea that words are actually quite meaningless but their interrelatedness somehow gave meaning to the things and experiences I had in life.
Whereas most people learn to distinguish fact from fiction by learning from others, I seem to have engendered a philosophy that word meanings and their roots have meaning to things seemingly unrelated in physical space. I was quite an odd kid.

June 28, 2013 - ... I think as long as it's labeled "Collegiate" you're going to find that it has the words you need for everyday use. If you're looking for etymology, history, etc. then the Oxford English Dictionary is the one for you.

r/vocabulary on Reddit: A Comparison of Online English Dictionaries
June 25, 2023 -

I did a preliminary comparison of Cambridge, Merriam-Webster, MacMillan, Collins, Longman Dictionary.com and Vocabulary.com.

DictionaryVariantWord ListSound QualityUI / Design
Merriam WebsterUSYesOkayGreat
CambridgeUK / USYesGoodDecent
Dictionary.comUSYesPoorVery Good
CollinsUK / USNoVery GoodVery Good
MacMillanUKNoDecent to GoodOkay to Decent
LongmanUK / USNoDecentDecent
Vocabulary.comUK / USYesExcellentGood to Very Good

The above table is for rough reference of my subjective opinion _____________________________________________________________________________________________________________________

Merriam Webster has really good looking website but oddly enough, doesn't present an example usage right below the definition. It does have a menu on the left and it is snappy to use so it is not that big of a deal. It also has a dedicated `Word History` section.

Cambridge is pretty basic and gets the job done. Shows accompanying images alongside—neat.
But it does somehow manages to look convoluted despite not having all that much extra information.

Dictionary.com has a clean looking website and is the only one that has phonetic respelling.
Awful quality of pronunciations, however; no idea why.

Collins has a well laid out website along with a `Word Frequency Meter` to the right of every word. There is also a chart at the bottom which plots usage over time.
Often has short videos showcasing pronunciation visually with mouth movements.
I might've gone with this one initially but lack of word list was a dealbreaker.

MacMillan....doesn't seem to have any benefits and really feels like a slightly crappier version of Cambridge to me. It is the only one where you cannot create a user account.

Longman dictionary looks very minimalistic to me in terms of information displayed.
It also has a simple word frequency meter (categorized by spoken / written usage).

And lastly, Vocabulary.com is my personal choice and for good reason.
First of all, there is an advanced search option that allows you to narrow down search results based on various parameters of a word (part of speech, start / end, no. of characters etc.). I can see this being a really handy power tool.
The first part is a short explanation woven with context, as opposed to the technical definition of it (which is provided below that along with images sometimes). I really liked this approach; helped me understand better.
In example sentences, the word in question is highlighted in bold (unlike italics in some dictionaries; which doesn't stand out as much) and you can even choose the source material (like fictions, sports, business etc.). Again, another handy addition.
Also often has short (and better integrated) short pronunciation vids like in Collins.
There is a `Word Family` section in this one which charts their relative frequency in terms of occurrence per pages but it is not that intuitive imo.
All in all, it checks of the basics and the sound quality is surprisingly crisp.
Website looks nice, nothing fancy here, but very functional I'd say.
For me personally, I was looking for a dictionary that contained British English definitions and had the word list feature. So this left me with two options, namely Cambridge and Vocabulary.com and I chose to latter due to aforementioned reasons.

Of course, these aspects are not exhaustive in any way, just those that I found relevant.
Just for clarification purposes, this post is not sponsored in any way and I was going to make a post asking for recommendations but decided to do it myself anyway. Thought it would serve as a guide for others.

I saw the Wiki of this subreddit.

The "Learner's Dictionaries" section says five online-dictionaries.

And I noticed that "Cambridge Learner's Dictionary" 's top page says that it is for learners of British English. But I'm not sure about other dictionaries.

 

For now, I am thinking of using American English.

Which dictionary should I use for American English ?

 

Note: (copy-and-paste from Wiki)

- Longman Dictionary of Contemporary English

r/dictionary on Reddit: Oxford dictionary choices
March 25, 2024 -

Hello all, I’m looking to pick up an Oxford dictionary but I am a little overwhelmed by choices. Compact, concise, English dictionary, dictionary of English, shorter, etc. What is the best format here? I need something fairly comprehensive, but limited to no more than a two or three volume set. A single book would also be fine. Vintage is also great as I collect older books Without getting my hands on them, it’s hard to distinguish the differences in all these variations. What would be your recommendation? Thanks!

It depends on what you want it for. These days, nothing can beat the websites: oed.com for the historical dictionary (which lists all the things a word has ever meant since its first appearance in English, so if you look up 'nice' the first thing you'll find is 'foolish, silly, simple, ignorant' because that is the oldest meaning) or premium.oxforddictionaries.com for the current dictionary. They contain all the latest information and discoveries and no book can measure up (if the current OED were printed, it would be twice the size of the 2nd edition of the OED, which took up 20 sizeable tomes). However, if you want a book, the Oxford Dictionary of English is your best bet for finding the meanings of words: https://www.oxfordreference.com/display/10.1093/acref/9780199571123.001.0001/acref-9780199571123 This dictionary lists what words mean now. The Concise Oxford English Dictionary is a much abbreviated version of the historical dictionary, which will give you historical information as well as the meanings. The Compact Oxford English Dictionary is an amazing artefact but not something you will want if you want to actually look up words: it's a huge book that contains the full 2nd edition of the Oxford English Dictionary with 9 pages printed to a page and a magnifying glass to be able to read it. Amazing in the day - it allowed people who couldn't afford a 20-volume set to own the full thing - but not really worth the effort now. The Compact Dictionary of Current English is basically the Oxford Dictionary of English, but smaller.
