Ablative: a certain case of Latin nouns.
The word derives from ablatus, which is from aufero, (to carry away), ultimately from ab (away) and fero (I carry).
In it’s original sense, we use the ablative case when describing actions of carrying something away, or taking something away.
However, the Ablative has many more uses. Most famously, the Ablative is used to drive students mad.
The “Ablative Absolute” is an ancient form of grammatical error much admired by modern scholars.
