It likely means "instigated again" or "restarted".
Here's a breakdown:
* Instigate means to cause something to happen, especially something bad or unpleasant.
* Re- is a prefix that means "again" or "back".
Therefore, "re-instigated" would imply that something that had been stopped or paused was started again.
For example:
* The protesters re-instigated their demonstrations after the government refused to meet their demands.
This means that the protesters had stopped their demonstrations, but started them again due to the government's actions.
Remember: "Re-instigated" is not a word that is commonly used. It's more common to say "instigated again" or "restarted".
