The Honorific Ending 시

The honorific pre-final ending is added to a predicate stem ending in a vowel is added to a predicate stem ending in a consonant. When 시 is added to a predicate's stem, the subject associated with the predicate is honored. A subject will often be honored consistent with their age or rank in society. As a result, the suffix 시 is often colocated with formal speech and honorific nouns.
