This is a type of question which is on-topic on ELU, "What's a word or phrase for...?" and we even have a tag for it: single-word-requests, along with its counterpart phrase-requests.
It's very important to follow the tag advice when asking the question. Many people doubt that these questions are a good fit, in that they are simply a look-up service. It's also easy to be lax in your specification of what you really need, which results in a large number of answers; many of those answers will be a waste of effort because they don't answer what you actually wanted (but failed to ask for).
The community has become more strict on requiring
- that the [ -request] tag be used, or added where the question author hasn't already;
- that the tag guidelines be followed.
A particular requirement which is often missed is a sample sentence, or the particular nuance of meaning required. This is actually missing in your suggested question; you've said what is not required — which is good information and should certainly be stated — but you haven't actually described what your word is attempting to relay.
Thinking about the details of what you actually want your word to say can often lead you to use just the right word in the question. That's fine: if you realise you have it, we've actually helped.
Because tag guidelines are amended periodically, there's not much point in quoting them here, especially when they are easily available from a link: Word requests | Phrase requests — phrase requests are very similar to word requests.
In particular, the checklist at the bottom of each guide is very important. Help the community to help you by being as specific as possible in your question.
To address your specific example, when you are considering what the man is doing, you might plaintively write, "...he's simply telling them something." And that gives you your word, tells. If it doesn't work for you, add that to the "not suited" list and say why it doesn't work.
