One root, a whole family
A single ancient root can seed dozens of English words. Take the Latin ped-, “foot”: it grows into pedal, pedestrian, pedestal, biped, centipede, expedite (literally to free the feet) and impede (to shackle them). Or Latin port-, “carry”: import, export, transport, portable, porter, report, deport. Grow plants one such root each day and challenges you to grow as many of its descendants as you can.
What makes it more than a word search is that the connections are often disguised. The Latin manus, “hand,” is obvious in manual but buried in manoeuvre (hand-work), manuscript (hand-written), and even manufacture (originally “to make by hand”). The Greek root behind photograph also hides in photosynthesis and phosphorus (“light-bearer”). Spotting the family resemblance across such different-looking words is the whole game.
Every word Grow accepts is machine-checked against Wiktionary's etymology data, and each word links to its source, so nothing has to be taken on trust; the colours mark each root's home language — the six strata of English. It's vocabulary the way etymologists actually see it: not thousands of separate words to memorise, but a few hundred roots endlessly recombined.
