tu
your
The Spanish word 'tu' is equivalent to the English word 'your'. It is used as a possessive adjective modifying a noun, indicating ownership or association. Note that 'tu' does not change to agree with gender, but it does change for number, 'tus' for plural. Also, Spanish makes a distinction between singular and plural ('tu' and 'vuestro'), and familiar and formal ('tu' and 'su'), which English does not make.
