Affixes are not mentioned until some familiarity with the general
character of the language is assured, as well as the possession of
a fair vocabulary. They are introduced gradually, with adequate
explanation and illustration. Of importance in connection with
word-formation is an element distinctly new--the explanation and
classification of compound words. Such words, like affixes, are
withheld until the use of simple words is familiar.

Another new feature is the gradual introduction of correlative words in
their logical order, and in their proper grammatical categories, before
they are called "correlatives," or tabulated. The tabulation finally
presented is a real classification, with regard to the meaning and
grammatical character of the words, not merely an arbitrary alphabetical
arrangement. The use of primary adverbs precedes the explanation of
adverb derivation; prepositions, especially "de", "da", "je", etc.,
receive careful attention, also the verb system, and the differentiation
of words whose English equivalents are ambiguous.

A general characteristic of obvious advantage is that almost without
exception new forms and constructions are illustrated by means of
words or roots already familiar. Likewise, the new words or roots of
each lesson recur at least once in the next lesson, and usually in
some lesson thereafter as well. Each reading exercise gives not only a
thorough application of the grammatical principles of the lesson, but a
review of those in the preceding lesson, and no use is made of words or
constructions not yet explained. The comparative ease of the language,
and the lack of necessity for reciting paradigms, permit the reading
exercises to be long enough for the student to feel that he has really
mastered something. These exercises are further unique, in that each
