Rahul (-n. rāhula), a popular male name in India, has a variety of meanings:
The earliest meaning found in the Upanishads is "conqueror of all miseries."
Later use of the word is attributed to the Lord Buddha, who named his son Rahula as he felt that family ties could be an obstacle in the path to renunciation and nirvana. Lord Buddha uttered Rahul when he first saw his son and gave a new meaning "relationship" and "bondage" to this name.
Rahul means Moon, Able/efficient in Sanskrit and Pali.
Rahul also means "Traveler" in Arabic.
