What is the meaning of 'stationary' and 'stationery' respectively?

Fixed, Writing material

The answer is ☀ Fixed, Writing material.

• Stationary is an adjective that means not moving or not intended to be moved.
• Stationery is a noun that refers to paper, envelopes, pens, and other equipment used for writing.

The two words are often confused because they sound the same. However, they have different meanings and are used in different contexts.

Stationary is used to describe something that is not moving. For example, you might say "The car was stationary at the traffic light" or "The patient was kept in a stationary position."

Stationery is used to describe writing materials. For example, you might say "I need to buy some stationery for my office" or "The stationery store was out of pens."

The other options are incorrect. Volatile means changing or unstable, and inkpad is a pad of ink used for stamping.
