Narrative:

Taxiing out for takeoff on runway 23R, we taxied onto active runway 28 which was regularly used as a taxiway to reach our assigned runway. The taxi clearance to runway 23R has always been 'taxi to runway 23R via taxiway U, runway 28, hold short of runway 23L.' the hold short line for runway 23L is on runway 28. The clearance we received today was 'taxi to runway 23R via taxiway U, runway 28, hold short of runway 28.' we received the clearance while completing our taxi checklist which includes the takeoff briefing. The 'hold short of runway 28' didn't register with us and we were further misled because the aircraft in front of us had taxied onto runway 28 as we approached.
