The word 'impractical' means something that is not useful or realistic in a particular situation. You can use this word when you want to describe an idea or a solution that is difficult to put into action and may not work well. For example, if someone suggests using a helicopter as a means of transportation to travel a short distance, it would be considered impractical because the cost and effort of using a helicopter would far outweigh the benefits of using such an expensive and elaborate mode of transport for a short journey.
