Springboard uses Esperanto, a living language, to build an awareness of language structure and grammar. For example, using the root-word rapid and the regular word-endings (all nouns end in o, adjectives end in a, adverbs in e, etc.) learners can build words themselves.
- rapida = fast (adjective)
- rapide = quickly (adverb)
- rapidi = to hurry (infinitive)
- rapido = speed (noun)
- rapidu! = Hurry up! (imperative)
As Esperanto is perfectly regular (no exceptions), pupils can easily calculate how many words they are able to create from one root and how many they could build by learning, say, five roots. In fact, by using simple affixes like mal- (opposite) and -ul- (person) they can easily manipulate the language and create lots more words.
- rapidega = (adjective) very fast/hurried
- rapidulo = (noun) someone in a hurry
- malrapide = (adverb) slowly (opposite of quickly)
- malrapideti = (verb) to slow down a little
