Esperanto does not ask you to memorise a warehouse of unrelated forms. It stores roots. Affixes are withheld until simple words are familiar — then they multiply what you know. mal- alone cuts the list in half.
Type any Esperanto word. Prefixes, roots, suffixes, and endings come apart.
Esperanto stores roots, not a warehouse of unrelated forms. From san- (health) you can build the hospital without memorising a new stem: mal-san-ul-ej-o — the place of unwell people.
