That's a hard question to answer, because, like you said, the word 'strike' has lots of meanings.
Here are some of the most common ones;
* To hit something
e.g. He looked like he was going to strike me.
* For a thought/idea to come into your mind suddenly or unexpectedly
e.g. It struck me that it might be a good idea after all.
* To cancel, remove or cross out
e.g. His name was struck from all records.
* To refuse to attend work or school in protest of something
e.g. The workers were on strike due to poor working hours.
* When a clock indicates the time with a chime or stroke
e.g. The clock struck twelve.
Hopefully that helps :)
