Esperanto
The International Language, taught in the order and manner of Kellerman's 1910 grammar: a fully regular alphabet, then the parts of speech marked by their endings, each rule explained rather than merely stated.
A1
The Alphabet, Diphthongs, and Accent
—The twenty-eight letters, each with one sound and one sound only; the six diphthongs; how consonant groups are sounded; and the single rule of accent from which no word departs.
Nouns, the Article, Adjectives, and the Present Tense
—Each part of speech announces itself by its ending: -o a noun, -a an adjective, -as a verb in the present. There is one article and it never changes; there is no indefinite article at all.
The Plural, and the Predicate
—One letter, -j, makes the plural of nouns and of the adjectives that go with them; the article and the verb stay as they are. A noun or adjective joined to the subject by *estas* is a predicate, and agrees in number with what it is predicated of.
CheckpointCheckpoint: Sounds, Endings, and Number
—A cumulative examination of the first three sections: the alphabet and its invariable sounds, the endings that mark the parts of speech, and the plural with the agreements it requires. Twenty-four questions in the four examination formats.
