su
their
The Spanish word for 'their' is 'su'. It is used to denote possessive aspects in a similar way as in English. Particularly, 'su' indicates that a noun belongs to them. However, it's important to note that Spanish doesn't make a distinction between his, her, its, your (formal) and their, using 'su' for all of these, so the exact meaning depends on the context.
