About
Words Grow is a dictionary you grow by reading, made for anyone hungry to read lots of English.
Read freely, save new words right where you meet them, and check them in an English-English dictionary. Every word keeps the context it came from, and your own dictionary grows with every page.
SAVE WORDS WHERE YOU READ
• Read Wikipedia's featured article of the day, or any English page, in the built-in browser
• Long-press a new word to save it
• Or select a word in Safari and tap Share → Words Grow
• Words you have saved show in bold green on every page, so you can see at a glance what you already looked up
DIG DEEPER WITH ENGLISH DEFINITIONS
• English-English definitions and examples from Wiktionary, by part of speech
• IPA pronunciation, plus a speaker button to hear the word
• Every word in a definition is tappable: follow one word to the next
• Inflected forms are saved as the dictionary form (running → run, leaves → leaf)
SEE THE TRAIL OF EVERY WORD
• A family tree shows the page you met each word on, and the words that led you to it
• Words from the same article and the same chain of thought stay together, which makes them easier to remember
• For each word, look back at the sentence, page and time you met it
YOUR OWN DICTIONARY
• All your words in one list, with how often you looked each one up
• Mark the words you have understood with a check
• Add words you met off the web, like in a book
• Definitions are kept on your device, so they open offline too
TRANSLATIONS, ONLY WHEN YOU WANT THEM
• See each sense translated into your language: Japanese, Chinese, Korean, Spanish, French or German
• Translations stay hidden until you tap, so you think in English first
30-SECOND TUTORIAL
• A short guided tour, available in English, Japanese, Chinese, Korean, Spanish, French and German
Definitions, translations and pronunciations come from Wiktionary (CC BY-SA 4.0).
