These are links to websites that English Language Learners can easily and quickly use– without having to register or sign-in (or download) — to aid them in spelling, pronouncing, learning the meaning, etc. of a word or phrase they are trying to read or write.

My students and I often find them very helpful. Having access to them provides a greater sense of self-reliance and confidence that they can find many answers (or confirmation of information they knew already) on their own and very quickly. And it dramatically reduces the number of “simple” questions I have to answer so I can focus on assisting students in higher-level learning or spend time with those who have special needs.

In addition, students can use these tools at home on their own computers or ones they have through our Family Literacy Project.

The basic criteria for a site to be on this list is this:easily accessible to English Language Learners; free-of-charge, and no registration or downloads are necessary to use the sites.

Before I start listing specific sites, here are a few other “Best” lists that could also be considered as “reference sites”:

The Best Search Engines For ESL/EFL Learners

The Best Resources To Learn About The U.S. Census (contains many accessible tools for researching U.S. demographic data)

The Best Multilingual & Bilingual Sites For Math, Social Studies, & Science

The Best Sites For Learning About Google Translate & Other Forms Of Machine Translation

Here are my choices for The Best Reference Websites For English Language Learners:


There are several simple text-to-speech tools out there. All students have to do is copy a word a few sentences from something they’re reading and paste it on one of these sites. They will immediately hear the word pronounced. Students can do the same with their own writing to double-check if it “sounds” right.

All these tools are similar — they don’t require registration, you can choose which “voice” it speaks, and it’s spoken in a fairly decent computerized tone:



Google has create a text-to-speech tool for web developers, but anyone can use its demo.



This section will focus on three types of tools — ways that students can learn the meaning of English words in their native language,  ways that students can find simple English or picture definitions of the words, and the best ways they can find synonyms or antonyms.  Of course, many of these sites offer more than one of these features, so I may appear to be a little arbitrary in deciding which category they fit.


These translating tools all work in a similar way — they let you copy and paste words or sentences, and then pick the language you want it translated into.   The translation then appears on the screen.   Some also let you translate entire webpages

Google Translate


Nice Translator is the newest addition to this list.  One way it stands out is by translating into your chosen language as you write it.  Most other similar sites require you to input everything and click “enter” before it begins to translate.

The ESL Reader and the amazing Lingro operate with the same perspective. Once you either copy and paste words (The ESL Reader) or input a url address (Lingro), then all the words become “clickable.” Once you click on a word, you see the the meaning of the word in the language of your choice — English or in a student’s native language.

Tradukka is a simple translation site. It’s just a re-packaging of Google Translate, but it’s a very nice re-packaging.  The interface is more attractive and accessible.



There are dictionaries that I think are particularly accessible to English Language Learners:

For Beginning and Early Intermediate English Language Learners, The Language Guide is clearly the best place to go. It’s easy to navigate, and has excellent images, audio, and text.

Ninja Words returns your query very quickly, and provides the basic information most people need. Its simplicity makes it attractive for high Intermediate and Advanced ELL’s.

Reverso is an online dictionary with lots of other features.

Merriam-Webster has a Learners Dictionary.

Innovate ELT 2021 – day two is from Sandy Millin. If you scroll down, there’s a lot of good information about online dictionaries for ELLs.

Maptionary looks like a cool visual dictionary and thesaurus.


Lexipedia is a pretty darn impressive site. This can fit under many of the categories in this section. You type in a word, and, in an engaging visual display, shows you a ton of information about that word and lets you get the audio of the word pronounced.

Visuwords is another unique, and fun, way to find synonyms in a visual display.  It’s free, and it also functions as a dictionary.

Snappy Words is a similar tool.

WordSift came out several years ago as a great tool to help English Language Learners develop academic vocabulary knowledge. Mary Ann Zehr wrote an excellent description of it at Ed Week, and I put it on The Best Websites For Developing Academic English Skills & Vocabulary. It was created by Stanford Professor Kenji Hakuta. Then, it seemed to disappear. I started getting requests from educators for alternatives. Now, it’s back! WordSift 2 has launched. Paste in a text, and you get all sorts of stuff in return — word clouds sorted in various categories, images of words to enhance understanding, sentences showing the words in context, word webs, and more!

Graph Words is a new very simple visual thesaurus. It’s not as fancy as some of the other similar applications out there, but I think some of those other sites are actually pretty confusing to English Language Learners.


I don’t quite know where to fit these next two web tools, so I’ll just list them here.

Tip Of My Tongue is an intriguing “dictionary-like” web application.  You can do a variety of things to identify a word or its spelling — actions that you couldn’t necessarily take with regular dictionary. For example, if you know the first letter and the last letter of a word, you would type them in and then the page will show the words (and their definitions) that fit those parameters.

The Rhyme Zone says it all with its name. It’s an easy way to find rhyming words and their definitions.

Describing words helps you find adjectives for words you want to…describe.

Power Thesaurus is a crowd-sourced…thesaurus that looks pretty good.


Depending on the information students are needing on countries of the world,  Infoplease Countries is good for basic data.

World Info Zone. It’s similar to the others, but the language might be a bit more accessible to English Language Learners.

Q-Files has good, basic and accessible info on all countries.


America’s Library from the Library of Congress gives a very short and accessible overview of each state.

For more detailed information, I’d suggest students visit Infoplease: States.

The Measure of America is the name of American Human Development’s website.  It has an extraordinary interactive map highlighting how states (or Congressional districts) in the United States rate in over sixty categories, including health, education, income, etc.  It might be a little tricky at first for English Language Learners to get the hang of it, but it shouldn’t be a problem with a little teacher assistance.


National Geographic has a nice section on cities throughout the world.



I know some people have issues with Wikipedia, but I’ve found the Simple English Wikipedia to be a great resource, and the most accessible to English Language Learners.  I’d also put Fact Monster on this list.

This next one isn’t really an encyclopedia, but I can’t think of any other category to put it in. I’m really quite impressed with Wiki Answers. It’s a huge and growing community composed of simple questions and their answers. All the ones I’ve checked have been accurate.

Credo Reference is like a mini-online encyclopedia. Its language is not as simple as I’d like it to be, but its big asset is that it provides audio narration for the text.



Language Tool is a grammar and punctuation checker. Google or Microsoft will point out the same mistakes.  However, Language Tool will also provide a short explanation of why it’s a mistake.

Suggestions are always welcome.
