"gash"
I don't normally learn from example or from experience. I need things spelled out directly in front of me in order to clearly get the point.
But gash is such a simple word. Just one meaning. Even rhymes with the cause of the one on my step-mom's stomach.
Car crash.
Gash.
And the ash from the engine fires that lit the grass.
Gash: a deep, long cut.
It's a little difficult to not learn that one from example.
