I think you will find that we Brits can usually enunciate “probably” very well. Together with most other “difficult” words.
We carry “brollies” to keep the rain off our heads and clothing. Casting an umbra from an umbrella is rarely needed in these climes.
Nevertheless, throughout the civilised world, that used to be painted red on the maps, a “brolly” is a synonym for an umbrella, which may serve dual-use, against sun, or rain.
