Correct pronunciation is "alogy" or "allergy" as described above. I usually pronounce it this way, but as with most of our spoken language pronunciation is fluid. I have been guilty of using the "ology" in conversation, but quite often correct myself.
As Jaybelnz said, as long as we know how it's spelt, and what it means.
I am Australian, from all the lands I come (my ancestors, at least!)
Pine/Pyne, Dowdeswell, Kempster, Sando/Sandoe/Sandow, Nancarrow, Hounslow, Youatt, Richardson, Jarmyn, Oxlade, Coad, Kelsey, Crampton, Lindner, Pittaway, and too many others to name.
Devon, Dorset, Gloucs, Cornwall, Warwickshire, Bucks, Oxfordshire, Wilts, Germany, Sweden, and of course London, to name a few.
