问题
Is there any way I can get a full list of hyponyms related to a single word?
relative = wordnet.synsets("relative", pos='n')[0]
hyponyms = ([lemma.name() for synset in relative.hyponyms() for lemma in synset.lemmas()])
This gives me quite a lot of hyponyms, but many that are in the full hyponyms list on Wordnet's online search are not in my list.

Use the Synset.closure() function:
from nltk.corpus import wordnet as wn
relative = wn.synsets('relative', 'n')[0]
hypos = lambda s:s.hyponyms()
print(list(relative.closure(hypos)))
