Hi,

I found the definition of "sleeping" and "sleep" from Answers.com,

A. sleeping: sleeping: Definition, Synonyms from Answers.com,

Within this link, it defined sleeping as "adjective",

B. sleep: sleep: Definition, Synonyms from Answers.com,

Within this link, it defined sleep as "noun" and "verb",
Please note that the verb definition of sleep: v., slept, sleepˇing, sleeps. , it also includes the sleeping in verb.

So, when I found a sleeping word in some sentences, what kind of meaning should I use? adjective or verb or gerund ?

For example: "Sleeping with the telephone", I always thought the "Sleeping" in here is a gerund before.

Thanks.
