§508. Supine
The Supine is a verbal abstract of the fourth declension (§ 94. b), having no distinction of tense or person, and limited to two uses. (1) The form in -um is the Accusative of the end of motion (§ 428. i). (2) The form in -ü is usually Dative of purpose (§ 382), but the Ablative was early confused with it.
