How does it change in a sentence?

The name is written using Katakana, which is the standard script used for foreign names and loanwords.

The romanization is Wiriamuzu.

While ウィリアムズ is the standard phonetic translation, some foreigners in Japan choose to assign 漢字 (kanji) characters to their name to give it a traditional Japanese meaning. This creates a personalized visual identity that goes beyond the phonetic Katakana.
In Japanese business contexts, ウィリアムズ would almost always be followed by the honorific さん (san). Even though 'Williams' is a surname, it is considered impolite to use it alone without this suffix.
Because Japanese does not have a standalone 'w' sound followed by 'i', the small ィ character is used in ウィ to create a blended sound. This is a specialized orthographic rule used specifically for foreign words.
