As of now, I'm not entirely sure what "canaverous" means as it seems to be an uncommon or perhaps misspelled word. Assuming it might refer to something related to being greedy or voracious, here are some possible synonyms and an analysis:
rapacious: This word implies being extremely greedy or predatory. For example, "The rapacious businessman was always on the lookout for new opportunities to make a profit." It conveys a sense of intense hunger or desire for more.
voracious: Similar to rapacious, voracious suggests a great appetite or hunger. For instance, "The voracious reader devoured books at an astonishing rate." It can be used to describe a person or thing that consumes or desires something in large quantities.
insatiable: This term means not able to be satisfied. For example, "Her insatiable curiosity led her to explore many different fields." It implies a never-ending desire or need.
greedy: A more common word, greedy simply means having an excessive desire for wealth, food, or other possessions. For instance, "The greedy child took all the candies for himself." It is a straightforward way to describe someone who wants more than they need.
If "canaverous" means something else entirely, without more context it's difficult to provide truly accurate synonyms.
