Decode • Connect • Apply • Transfer
Use roots as meaning clues, then test them in real context.
Root Discovery Map
Six root families. Twelve target words.
uni = one
unilateral - done by one person, group, or side
unify - to bring together into one
bi = two
bilateral - involving two sides or parties
biennial - occurring every two years
tri = three
trilateral - involving three sides or parties
trilogy - a group of three related works
multi = many
multifaceted - having many different aspects
multitude - a very large number of people or things
metr = measure
metric - relating to a system or standard of measurement
symmetry - balanced proportions or correspondence of parts
quant = how much
quantify - to express or measure as a quantity
quantitative - relating to numerical measurement
