About
Learn the root spect and inspect, respect, prospect and spectacle come with it. Rootword draws 80 roots and over 1,300 words as relationship maps, and takes each word apart honestly: which part is the root, which the prefix or suffix, and why the pieces mean what they mean together.
Spaced repetition schedules review; new words are checked with multiple choice where the distractors are from the same family, so guessing does not work. Listening mode plays roots and examples on the lock screen for walks.
Junior-high vocabulary and the spect, port and dict families are free; one purchase unlocks everything.
