The predicative form is marked by the suffix -u: urbo megu "(the) city is big", lampo pendu "(the) lamp is hanging".
As in Esperanto, the attributive form is marked by the suffix -a: mega urbo "big city", penda lampo "hanging lamp".
Possessives take the -j- that converts nominals to verbals as well as the attributive -a: mi "I", mija "my, mine"; vi "you", vija "your, yours"; al "he", alja "his"; la "she", laja "her, hers"; lo "it", loja "its", etc.
Plurality and pluractionality may be shown through reduplication, usually partial: tatablo (or tablo-tablo) "tables", dendeno or dedeno "days", kloklora "of many colours", marmarʃu "walk repeatedly".
Oblique case (direct and indirect objects) may be marked by nasalisation of the final vowel of the noun and also of any attributives: ʒədonu zeã librõ "give this book!".
In a few words gender is marked by a, infixed before the last consonant for the masculine (tigar or tigaro "male tiger"), suffixed and stressed for the feminine (tigrá or tigráo "tigress").
As in the Semitic languages, vocalic ablaut derives roots with related meanings, such as lina "long", lana "wide", and lona "tall", or valdo "forest", veldo "savannah", and vildo "steppe".
However, a number of frequent compounds are contracted into new roots: dennedo → dendo "day and night", evdeno → evdo "morning", evnedo → evno "evening", evzaro → evzo "spring", evrazo → evro "autumn".
