# LINK_ROOT

*LSL constant*

```lsl
integer LINK_ROOT = 1;
```

Refers to the root prim of the linkset.

Constant groups: [Link](/constants/groups/Link/), [Links](/constants/groups/Links/)

Targets the root prim in the linkset.

## Caveats

- In a single prim object `LINK_ROOT` will not refer to the root prim!
- If your script needs to work in single and multiprim objects, instead of `LINK_ROOT`, use either `(llGetLinkNumber() != 0)` or `(!!llGetLinkNumber())`
- Alternatively, [LINK_THIS](/constants/LINK_THIS/) works in both single-prim and multiprim objects, assuming the script is inside the root prim and only needs to refer to itself.
