DIVISION II.—ABBREVIATED LATIN DERIVATIVES.
NOTE—In Division II, the English derivatives from Latin roots are given in abbreviated form, and are arranged in paragraphs under the particular radicals, from which the several groups of derivatives are formed. The radicals are printed at the left in bold-face type—thus., acr-, acerb-, etc. Derivatives not obviously connected with the Latin roots are given in the last paragraph of each section. Pupils are required to unite the prefixes and suffixes with the radicals, thus forming the English derivatives, which may be given either orally or in writing. Only difficult definitions are appended: in the case of words not defined, pupils may be required to form the definition by reference to the signification of the radicals and the formative elements, thus, acr + id = acrid, being bitter, acr + id + ity = state of being bitter, bitterness.
