What does "strike home" mean?

Solution 1:

Previous answers suggested that

This example ought to strike home for you

means "This example should be understood by you" or "You should immediately understand this." It's possible that's what the writer meant, but if so, the writer hasn't phrased the sentence well. It's unlikely an informed native speaker would say such a thing with such a meaning.

The fact that ngrams for strike home for you shows no usage of the phrase reinforces how unlikely it is to occur, regardless of meaning; but note that the sentence could arise naturally in dialog like

Solution 2:

Literally, strike home means to deal an effective blow, hit a vulnerable part, or wound critically or mortally.

Figuratively, as in your example, it means to have the intended effect, to hit the mark, or to cause a sudden understanding.
