In language learning, the principal parts of a verb are those forms that a student must memorize in order to be able to conjugate the verb through all its forms.
Famous quotes containing the words principal and/or parts:
“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
—Denis Diderot (1713–1784)
“We have seen that men are learning that work, productivity, and marriage may be very important parts of life, but they are not its whole cloth. The rest of the fabric is made of nurturing relationships, especially those with children—relationships which are intimate, trusting, humane, complex, and full of care.”
—Kyle D. Pruett (20th century)
