The word "pilger" is not a commonly used word in English. However, it can be spelled as /ˈpɪldʒər/ using IPA phonetic transcription.

Although the word may not be familiar, understanding its phonetic spelling can help with pronunciation in case you encounter it in the future.
The word "pilger" is derived from the Middle High German term "bilger", which was a noun meaning "pilgrim". The Middle High German "bilger" had its roots in the Middle Low German "bilger" and Old High German "piligrīm", both of which denoted "pilgrim". These Germanic terms were borrowed from the Latin word "peregrīnus", meaning "foreigner" or "pilgrim". The Latin word itself was derived from "pereger", which consists of "per" (meaning "through") and "ager" (meaning "field"). Ultimately, the word "pilger" traces its origins back to Latin and has undergone various phonetic changes and adaptations throughout the Germanic languages.
