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.

When the honorific suffix 시 precedes the past tense ending, the ending becomes 셨 or 으셨.

Even though a subject may be honored, the predicate itself may be conjugated in informal speech. In the following phrase, the predicate's subject is honored while the predicate itself is conjugated in the plain speech level.
