Occasionally I have cause to do a deep dive into word meanings.
Hope as a concept means 'confident expectation' and relates to the idea of respectful acknowledgement of one's duties and obligations, especially as owed to someone greater than you, prostrating one's self to show this service.
True relates to the word tree in the sense that a tree is not easily moved, compared to a stone boundary marker for instance. Possibly also relates to health in the sense of wishing someone to be as healthy (strong) as a tree.
False (to falsify) relates to the idea of deceiving someone, and the word fall(s) with the idea of causing someone to stumble by your lie (from the idea that they lie down unintentionally after stumbling).
Disclaimer: These are my opinion, based on known etymologies but extending the meanings based on known historical cultural practices, etc.
