In the phrase “I am broke” – why broke, but not broken?
Good time for your visiting italki, can I ask a question? In the phrase “I am broke” (meaning without money) – why broke, but not broken? Is a participleII from break is broke in British?

Question

Answer

There's no real grammar rule - we simply say "I am broke" to mean we have no money.

If we say "I am broken" (and yes, we can say this), it has an entirely different meaning: emotionally ruined, and unable to function as a human being.

Answer

'broke' in this context is an adjective, not a participle

Answer

"not broken"means his spirit is still strong and he still has a desire to go on living...to "be broken" may mean he no longer cares about anything,maybe even life itself.
