Esperanto helps with that by being polysynthetic and allowing you to attach suffixes to extend words (agglutination)
For instance:
good - bon+e (-e makes adverb)
bad - mal+bon+e (mal- is like un-)
very bad - mal+bon+eg+e (-eg- intensifies)
to make bad - mal+bon+ig+i (-ig- makes active, -i makes a verb)
to make worse - pli+mal+bon+ig+i (pli- means more)
you can also string roots together like in German: man+sak+o = hand+bag+noun suffix = purse/handbag.
this, and the familiarity of the roots to Indo-European speakers, makes Esperanto very fast for Europeans to learn. a small number of roots and good grammar gives you a lot of return on your time.
