West Germanic is a term used to describe a branch of the Germanic languages family. It comprises several languages like English, German, Dutch, and others. Instead of using the term West Germanic, there are other synonyms that can be used to refer to this group of languages. One of the synonyms is "Irminonic" which is based on the English deity Irmin and refers to the tribes that spoke this language in the early medieval period. Another synonym is "Ingvaeonic" which refers to the language spoken by the Ingaevones, a tribe that resided in what is now the Netherlands, Denmark, and Germany during the Roman Empire era. Lastly, "North Sea Germanic languages" is another term that describes the group of languages spoken by the Germanic tribes along the North Sea coast.
