The existence and use of 它 (tā) highlight a clear linguistic distinction between humans and non-humans in Chinese. While English speakers frequently personify their pets by calling them “he” or “she”, the grammatically standard and traditional Chinese approach is to use the neutral 它 (tā). This is not to say Chinese culture values animals less, but rather that the language's structure maintains a more formal separation. Using 他 or 她 to refer to a beloved pet is a modern, informal trend, often seen as a sign of endearment and Western influence. However, in any formal writing or when referring to animals in general (e.g., in a nature documentary), 它 is the only correct choice. This subtle difference shows how language can reflect underlying cultural perspectives on the relationship between humans and the natural world.
它 is used in three main contexts, which directly mirror the English “it”.
The formality is neutral. 它 is used in all registers, from casual conversation to formal academic writing.
