What is the vocabulary of hint?

I'm curious to know, what exactly constitutes the vocabulary of hint? Are we referring to a set of specific words or phrases that subtly convey a message or suggestion without directly stating it? Or does it encompass a broader range of communication techniques, including body language and tone of voice, that can also hint at something without being overt? I'm eager to understand the nuances and intricacies of this concept and how it applies to various situations in both cryptocurrency and finance.
