只 vs 条 (zhī vs tiáo): animal classifiers
Both 只 and 条 are measure words for animals, but they classify by body shape. 只 is used for animals with a compact, round body shape (e.g., cats, birds), while 条 is used for long, slender animals (e.g., fish, snakes). Some animals like dogs can take both, with 只 being more common and 条 emphasizing the elongated shape.
In Chinese, classifiers (measure words) are required when counting animals. The choice between 只 and 条 depends on the animal's shape: 只 is used for animals that are relatively compact or round, such as cats, birds, and insects; 条 is used for long, narrow creatures like fish, snakes, and worms. Some animals, like dogs, can use either classifier, but 只 is the default in everyday speech, while 条 emphasizes the elongated body. The general rule is ‘body shape over species’, but a few animals (e.g., horses, elephants) have their own dedicated classifiers.
When to use each
Use 只 for animals that have a compact, round, or non-oblong body shape. This includes most birds, mammals like cats, dogs (common), and also small animals like mice and insects. It is the default classifier for many household pets and common animals. 只 is also used for one of a pair (e.g., one hand, one shoe) but that is a separate usage.
For dogs, 只 is the most common and neutral choice. 只 is also used for mythical animals like dragons in some contexts, but 条 is more typical for dragons due to their long shape.
Use 条 for animals that are long and slender in body shape, such as fish, snakes, earthworms, and tadpoles. It can also apply to some mammals like dogs (to emphasize the long body) and to animals like crocodiles. For animals that can take both, 条 highlights the elongated shape, while 只 is the neutral default.
Some long animals (e.g., dogs, dragons) can be used with either 只 or 条, but the choice depends on the speaker's focus. Cats are never considered long animals; 一条猫 is incorrect in standard Mandarin. For fish and snakes, 条 is the only natural classifier.

Examples
- 只我有一只猫。Wǒ yǒu yī zhī māo.I have a cat.Cats always use 只.

Common mistakes
- Using 条 for a cat (一条猫) – cats are not long animals; always use 只.
- Using 只 for a snake (一只蛇) – snakes are long and slender; use 条.
- Assuming all animals use 只 – some animals like fish and snakes require 条.
- Thinking 条 is only for water animals – 条 is for any long creature, e.g., snake, worm, dragon.
