The spelling of the word "ex tolling" can be a bit tricky for non-native English speakers. The correct pronunciation of this word is /ɛks ˈtɒlɪŋ/. The "ex" is pronounced as "eks" and the stress falls on the second syllable. The "t" in "tolling" is pronounced as a silent letter, making the word sound like "tow-ling" rather than "toll-ling". The prefix "ex" means "former" or "out of", while "tolling" refers to the ringing of a bell or the sounding of a warning.
