The definition is at the end of the clue.
How the clue works
The definition is sex, since carnal knowledge is a euphemism for sexual relations. Thomas Telford, the famous engineer, had a lot of CANAL KNOWLEDGE, and inserting R (Romeo in the phonetic alphabet, 'attract Romeo') into CANAL turns it into CARNAL, giving CARNAL KNOWLEDGE.
