Part of Speech: Noun
In more advanced contexts, "lode" can also refer to any rich source of something valuable, not just minerals. For example, you might say someone has a "lode of knowledge" if they know a lot about a certain subject.
While "lode" itself does not have common idioms or phrasal verbs associated with it, you might encounter phrases that use "source" or "treasure" that convey a similar meaning of valuable resources.
"Lode" is an important word when discussing valuable resources found in the earth, particularly in mining contexts. It can also be used metaphorically to describe a rich source of knowledge or information.
