Common error
Avoid using "essential form of sustenance" when you actually mean "essential form of subsistence". While sustenance refers to the nourishment or support itself, subsistence refers to the state of remaining alive at a minimum level. Use sustenance when focusing on the quality or nature of what is being consumed.
