It also has a more specific definition: "the act of deliberately establishing an emotional connection with a child to prepare the child for child abuse".

Today, I think people are using the word to mean a hybrid of the above two definitions, namely, to train or indoctrinate a child into sexual deviancy, even if the person doing the grooming does not take part in it directly.

I think some uses today are also just synonyms for indoctrination, which fits only within the more general definition of grooming.

False accusations of child abuse have on occasion led to jail time for the false accuser.
