I'm new to this but I have a question, when someone only tells you part of the truth for example a conversation:
Me: hey I bought a new car
Saying I bought a new car, but hiding the fact that its second hand. I remember someone telling me this and that the media does it. Is this shadowing or something?
You can describe this as telling half-truths:
A deceptive statement, especially one that is only partly true, is incomplete, misrepresents reality by telling part of the truth, or alters the time sequence of truths.
Or, if you want to be more general, you can call these statements deception.
I think your example is flawed: if you say "I bought a new car", then it's a lie, plain and simple. However, if you point to it and say "That's my new car", it's not a lie at all.
This is because 'new' can mean 'newly built' or 'newly acquired'. So if you say "I bought a new car", then 'new' has to mean 'newly built', because 'newly acquired' is redundant -- you just bought it, after all. But "That's my new car" can legitimately mean "That's the car that I just bought." In this case, you might be asked, "What, new new?"
