The spelling of the word "HMWUK" is rather unusual and confusing to those unfamiliar with it. It is pronounced as [heɪm wʊk], with the 'h' and 'm' being pronounced individually. The 'w' is pronounced as a single sound, as in the word 'wet'. The 'u' is pronounced as in the word 'book'. The 'k' is pronounced like the 'k' in 'kite'. Despite its unconventional spelling, the acronym HMWUK stands for a popular UK-based organization that provides support for homeless people.
