Rootwise vs FlipDict

Most long English words are built from Latin and Greek parts. Learn the parts, and you can work out words you have never seen. Rootwise teaches one root a day. SPECT means "to look". Now inspect, spectator and retrospect make sense, and so does circumspect: careful, looking all around before acting. FIND YOUR NUMBER - A 2-minute placement test estimates how many words you already know - Fake words in the test catch guessing, so the estimate stays honest - One number to grow: the words you can decode LEARN A ROOT, DECODE A WORD - Each root comes with words you already know, so it sticks - Then decode new words from their parts and pick the right meaning - Every answer shows the real definition and an example sentence - Missed words come back in spaced review SEE THE FAMILY - The roots map shows every root and the words it unlocks - Trap words: look-alike roots with different origins, like PED (child) and PED (foot) - Share a card with your word count BUILT FOR - SAT, GRE and GMAT verbal prep - English learners who want to read faster - Anyone who wants to sound sharper at work PREMIUM - Every root is free to learn - Premium unlocks the last word of every root: 209 roots and 1,300+ words - $1.99/week or $3.99/month, no free trial, cancel anytime Your progress stays on your device.
