How are we, the British, expected to pronounce the above? Should it be mawl? Should it be mal? Both of these seem to make us self-concious.
It seems television may hold the answer: news anchors and the like seem to be settling upon a pronunciation apparently sympathetic to our American friends: marhl. It rhymes with Carl and Roald Dahl, and it seems like a fairly good compromise. This is how all the oddities of language begin.
Of course, television is not to be trusted. For example, the BBC have standardised on the pronunciation of CONtroversy, whereas Sky are going with conTROVersy. So who knows?
