A grammatical case in some languages (like Latin) that expresses separation, removal, or the agent performing an action; also can describe something capable of being worn away.
From Latin 'ablativus,' from 'ablatus' (carried away). The Romans named this case because it dealt with 'carrying away' or separating.
The ablative case is why Latin survived so long—it's so efficient at showing relationships between words that scholars used it for 2,000 years to write everything from poetry to laws.
