I'm really bad with words, especially with English words. Currently I'm struggling to make a good weapon names for my game, it needs to display the weapon functionality (weak/strong/fast/ballistic etc) correctly as well. For example the best weapon in a (futuristic) game cannot be called just with the name "Laser", it's just too boring, right?

Are there any tools, websites or anything that helps me finding good names for weapons? (or anything else similar).

I was thinking to use scientific names, but noticed that they are really hard to write, and they get very long, and I also lack information about science, I only know I could use the atomic sub-particles names in the weapons for example.

How do I get started with becoming good with making up names? (this could apply in generally to any naming problems).
