- In these extracts the word abuse is used in the sense of ‘an individual piece of invective’ or ‘an abusive comment’ and is clearly a countable noun.

The mathematics sense by which finite sets are countable is more common than the sense by which finite sets are not countable. To avoid ambiguity, the terms at most countable or countably infinite may be used.
