से marks the instrumental, ablative, and comitative cases.
# Functions
The three cases that से marks encompass several functions. से is arguably the most polysemous postposition in Hindi and thus classifying its various uses is very much an ongoing process.
When से marks a secondary argument to the verb, ascertaining the function can be difficult. This table, adapted from Khan (2009), is a guide for that.
| Subject Marking | 2nd Arg Marking | Example Predicates | Function | Scene Roles (predicate-licensed) |
| :-- | :-- | :-- | :-- | :-- |
| NOM/ERG, DAT | ABL | डरना, शर्माना | [ss Source] | [ss Stimulus] |

| NOM/ERG | COM/DAT | बात करना, कहना, मिलना, शादी करना | [ss Ancillary] | [ss Agent], [ss Recipient], [ss SocialRel] |
| NOM/ERG, DAT | COM | प्यार करना, नफ़रत करना | [ss Ancillary] | [ss Stimulus] |
