Alright, let’s break this down:

- Mere words

Just saying something, no matter how threatening, isn’t enough by itself to count as assault. Words alone can’t make someone fear immediate harm unless there’s a physical gesture to back them up.

- Mere gestures

Now, if you make a threatening gesture, like raising your fist at someone, that can actually amount to assault—even if you don’t say anything. The law cares about creating a real apprehension of harm.

- Mere preparation

Planning or preparing for an assault doesn’t count. You have to actually do something (like making a move or gesture)—preparation alone isn’t enough.
