Because this is a Lojban-English dictionary listing.  What does "terdi
bolci" mean?  "terrestrial sphere".  To translate the Lojban, you need
the adjectival English meaning.  Then in turn, the English order entry
for terresrial will also list "terdi".  Sure "pe le terdi" might also
work, but no one will look up "pe le terdi" in a dictionary - they will
look up terdi by itself.
