There is a common misspelling found in the phrase "most intrusted." The correct spelling is "most entrusted," with a silent "e" in the middle of the word. This is because the word "trust" is pronounced with a long "u" sound as /trʌst/ in IPA phonetic transcription. When adding the "-ed" suffix to form the past participle, the "e" is added to maintain the pronunciation of the root word. Therefore, it is important to be careful when spelling "trusted" and "entrusted" to avoid common errors.
The phrase most intrusted is not a word, but a combination of words formed by adding the superlative suffix -est to the word intrusted. Intrusted itself is the past tense form of the verb entrust. It is derived from the Old French word entrecoster, which means to put someone under protection or to assign a task to someone. The Old French term can be further broken down into entre, meaning between or among, and coste, meaning guard or protection. Ultimately, the word intrusted can be traced back to the Latin word custodire, which has a similar meaning of to guard or to keep safe.
