Pronunciation: [kˈiːsə] (IPA) 
The spelling of the word "keyser" is an example of non-standard English. The correct spelling is "Kaiser," which is a German word meaning "emperor." The IPA phonetic transcription for "Kaiser" is /ˈkaɪzər/, with the stress on the first syllable. The spelling "keyser" may be a result of a mispronunciation or a regional dialect. However, it is important to use standard English spelling to avoid confusion and promote clear communication.
The word "keyser" is a variant spelling of the term "kaiser", which is derived from the German word "Kaiser". The German word, in turn, comes from the Old High German word "keisar" and the Latin word "caesar".
The Latin term "caesar" originally referred to a title granted to Julius Caesar after he became the dictator of Rome. Over time, the title became associated with the Roman emperors and was adopted by various Germanic and Slavic languages to refer to an emperor or ruler.
In German, the spelling evolved to "kaiser", and it was used to denote the Holy Roman Emperors who were elected emperors of the German Empire. The term later gained prominence in the form of "Kaiser" through the German Empire established by Wilhelm I in 1871.
