The Allen and Greenough is still under construction;

ROOTS AND STEMS.
228.
Roots[1][For the distinction between Roots and
Stems, see ยงยง 24, 25.] are of two kinds: -
1. Verbal, expressing ideas of action or condition (sensible phenomena).
2. Pronominal, expressing ideas of position and direction.
From verbal roots come all parts of speech except pronouns and certain
particles derived from pronominal roots.
