What part of speech is “sleeping”

'sleeping' as a noun can sometimes be mistaken for its verb or adjective forms. Context usually clarifies its intended use. Compound terms like 'sleeping bag,' 'sleeping pill,' or 'sleeping pattern' use 'sleeping' as a modifier, but in the phrase 'the importance of sleeping,' 'sleeping' acts as a noun. Avoid redundancy. For instance, 'He is in a state of sleeping' is redundant; 'He is sleeping' or 'His sleeping state' would be more concise.
