In Latin, the ablative absolute is usually found at the beginning of a sentence. It consists of a noun and a participle in the ablative case.

The ablative of accompaniment requires the appropriate case endings on the affected noun, and the preposition 'cum', which means 'with'. But the ablatives of instrument and of means require only the appropriate case endings on the affected noun. Neither one needs any preposition.

An ablative absolute refers to a construction in Latin that consists of a noun and participle or adjective in the ablative case, which is syntactically independent of the rest of the sentence. One can go to the library or search the internet to find an ablative absolute.

An ablative noun is a noun that is moving away from something. In English we mark it with the preposition "from". In Latin it's marked synthetically, i.e cactus changes to cacto in the ablative case.

An ablative absolute is a construction in Latin where an independent phrase with a noun in the ablative case contains a participle, which agrees with it in gender, number, and case.
