When the digraph "ch" is pronounced as /ʃ/ (the "sh" sound) in English, it's a strong indication that the word has French origins. These words are typically loanwords, meaning they were adopted directly from French without significant phonetic changes.
Loanwords: Many English words with the "sh" pronunciation of "ch" were borrowed from French after the Norman Conquest.
Examples: Words like "chef," "machine," "chateau," "chandelier," "chagrin," and "chic" all demonstrate this pattern.
