“ THE BUILDING OF ENGLISH WORDS.The root of a word is the shortest form in which it appears. Thus tal, meaning number, speech, is the root of tale, a number counted; tale, a story; tell, narrate; toll, something counted out; talk, discourse.The root of a word may undergo modification and become a stem. Thus love is the stem of the root lov-, and to this stem are added such inflections as -est, -s, -d, as loves, lovest, loved.Again, to the root of a word may be added a prefix or suffix, thereby forming a new word called a derivative. ”
