The word "hosler" is spelled with an "s" instead of the more commonly used "z", as it is derived from the Middle English word "hoseler", meaning "innkeeper". The pronunciation of the word is /ˈhɒzlər/, with the stress on the first syllable. The "o" in the first syllable is pronounced as a short "o" sound, while the "e" in the second syllable is silent. The spelling of the word may seem unusual or archaic to some, but it reflects its historical origins.
The word "hosler" has its origins in Middle English. It is derived from the Old English word "hosle", which referred to a person in charge of maintaining horses or a stable. The word ultimately comes from the Old Norse word "hrosskoli", which meant "horseman" or "stable keeper". Over time, the word evolved in Middle English to "hoselere", and later to "hosler". The term was commonly used during medieval times to describe individuals who worked with horses and managed stables.
