It's e its: la regla del apóstrofo
It's = it is o it has. Its = de él o de ella (posesivo). Sin excepciones.
It's es una contracción. Siempre significa "it is" o "it has". Lee la frase en voz alta: si encaja "it is", usa el apóstrofo.
Its es posesivo, como his, hers o theirs. Sin apóstrofo. "The dog wagged its tail."
La gente se confunde porque el apóstrofo suele marcar posesión (Sarah's book). Los pronombres posesivos nunca llevan apóstrofo.
Prueba la sustitución: "The company updated it's website" queda "The company updated it is website." No funciona. Así que es its.
Examples
The dog wagged it's tail.
The dog wagged its tail.
Its a beautiful day.
It's a beautiful day.
Frequently asked questions
