The spelling of the word "EX B" is a bit unusual and requires careful attention to its pronunciation. In IPA phonetic transcription, it is written as /ɛks bi:/ or /ɛks bi/. The "EX" sounds like the beginning of "extra" and the "B" is pronounced as the letter's name. This word is typically used in legal documents and refers to a former spouse. While the spelling may seem confusing at first, once you know how it sounds, it becomes clearer.
