Question

Answer

The difference between penetrate, pierce and puncture. I have found it best to think of them this way:
Penetrate: 'To go completely, into, or through something.'

Pierce: 'To go through just the outer most membrane or the first layer'

Puncture: 'To break the first layer, but not go through.'

Answer

You can study these words with a dictionary.
