Each dictionary entry includes the word’s translation, part of speech and a corresponding image. You’ll also get example sentences and videos where it’s used. Both the word and example sentences come with audio pronunciation by a native speaker, which you can play at normal or slow speed.

7. Speller


Access on: iOS

Price: Free

Speller mainly allows you to check word spelling, but not grammar, so be sure to keep an eye out for that yourself. It checks both English and Spanish spellings and provides suggestions for words it doesn’t recognize to help point you in the right direction.

At the same time, it has a built-in dictionary, which makes it a handy two-in-one tool for when you want to check the spelling and definition of a word at the same time.

Spanish Spell Checkers to Supplement Your Dictionary App

When you need to look up the definition of something, dictionary apps are essential. But when you’re typing out the words you got from the dictionary, and you want to make sure that everything looks up to snuff (and not commit silly mistakes like mixing up pero with perro), you can also use spell checkers like:

  • Microsoft Word (iOS | Android). Aside from being a word processor, Microsoft Word offers a Spanish-language spell checker that doubles as a grammar checker. Also, you can select your country of choice from a huge array of Spanish-speaking countries, so this is a helpful way to ensure your grammar and spelling are regionally appropriate.
  • Gmail (iOS | Android). Gmail isn’t just the world’s most popular email service. It also has a built-in Spanish spell checker. To access it, create a new message, click the vertical three dots on the lower right hand portion of the window, click “Check spelling,” click the downward arrow beside “Recheck” and change your language to “español.”
  • Google Docs (iOS | Android). Google Docs is a popular, free alternative word processor that also offers Spanish spell check. To change your document’s language settings, just click “File,” select “Language” and scroll down until you find the variant of “español” you need. However, note that Google Docs’ checker isn’t completely foolproof, as it can miss grammar errors like gender agreement.
  • Google Chrome (iOS | Android). Chrome is similar to Google Docs, in that it can catch basic typos but gloss over grammatical errors. To activate Spanish spell check in Chrome, click the three dots at the upper right corner of your browser, then “Settings,” then “Languages.” Click “Add languages,” choose the regional variant of Spanish you want and click “Add.” Finally, make sure “Use spell check for” the Spanish dialect you’re using is turned on.
  • LanguageTool (iOS). LanguageTool is another good online option for your Spanish spell checking and grammar checking needs. Simply pick “Spanish” from the dropdown menu, enter your text and watch it detect issues like spelling and grammar errors (though gender agreement isn’t its strong suit).

Using Your Spanish Dictionary App

  • Fill in the blanks. When you forget the word, look it up! It’s as simple as that. Sometimes you’ll just need some instant gratification so your conversation (or thought process) won’t shudder to a sudden halt.
  • Set a time limit. Let your brain struggle and flounder to recall vocabulary and grammar on its own. This teaches your brain how to dig for important linguistic information. If you give up too quickly, you will no longer have this skill. That being said, you don’t have to be too strict about not looking up information. Give yourself a certain amount of time. If within, say, 2-3 minutes you can’t break through your brain block, you can resolve to look up that pesky word.
  • Keep the brain train working. When trying to recall a vocabulary word—even if you’re alone—talk or think your way as close to the word as humanly possible. For example, if I were trying to think of the word “catnip” in English, I might try to describe it by saying something like, “It’s that plant stuff you give to cats and it makes them go totally crazy. It’s like a drug for cats…” Then, I’d just keep going around and around until I finally have the word pop into my brain, or until a conversation partner clues me in.
  • Always have a “word of the day.” Some of the dictionary apps reviewed below have a “word of the day” feature on their home screens or have a connected social media company profile that provides followers with daily vocabulary. If you don’t get one automatically, browse and select a random word every day. Copy down the word and its definition in a notebook and keep a running list.


Now that you’ve found a dictionary, find something to translate! Having a good dictionary handy helps you enjoy authentic native content like books and movies. And watching Spanish media is a fun way to learn new words and phrases in the language.

Whether you’re chatting with Spanish-speaking friends or watching Spanish language content, a good dictionary will help you keep up during your language practice.
