Narrative: We received a dispatch release with the following flight plan: CVG-MUMIE-LOVEY-CADIZ-OBK. ATC sent our clearance over ACARS as: '- LOVEY5 CADIZ - CVG-LOVEY5-CADIZ.' I programmed the computer with the LOVEY5 departure then to CADIZ. With the following waypoints: CVG-LOVEY5-LOVEY-CADIZ the Captain and I reviewed the waypoints and agreed with it.[After departure] [w]e received a call from ATC querying our routing; and we told them. They then informed us we were supposed to be on the CADIZ TRANSITION. They vectored us around traffic; no traffic near us per TCAS; so no imminent threat. ATC then questioned us on this because they have been experiencing multiple deviations from [our pilots] on this particular departure. We were still working out what went wrong [but] the flight continued with no further problems. ATC did not give us a number or anything; but they said they were going to look into because this is becoming a recurring deviation.When I look back at it; I find: The dispatch release is a modified LOVEY5 departure; when we received the ATC amendment we [understood it] to add in the missing fixes to LOVEY then CADIZ. Dispatch should use the entire departure not portions of it. The ATC change [modified segment] states '-LOVEY5 CADIZ-' which; with our release; easily implies (or at least it did to us and apparently others who made the same deviation) [cleared] to LOVEY by LOVEY5 (which encompassed looking at INITIAL CLIMB and ROUTING on the departure) then CADIZ. I really think they should state 'CADIZ TRANSITION'; because we took it [CADIZ] as just a fix; not an entire procedure. When we reviewed the fixes we followed the departure SID to LOVEY then switched to the dispatch release with CADIZ; I should have looked at the two routes past LOVEY and queried ATC as to a more detailed routing; the only problem is that neither the Captain nor I had any questions or second thoughts on the routing.




Synopsis: The flight crew of a CRJ misinterpreted their revised PDC clearance out of CVG to read 'fly the LOVEY SID to LOVEY; thence direct CADIZ on course.' When they departed LOVEY ATC advised the clearance read 'LOVEY5.CADIZ' which clears them to fly the LOVEY SID; CADIZ transition; then provided vectors on course. Per the reporter ATC advises this is a frequent deviation on this SID.
