Usage notes 
The honorific form of verbs expresses the social superiority of the subject of the sentence to the speaker. As applied to adjectives, it expresses the relationship between the modified noun and the speaker.
For all but a few verbs and adjectives, the honorific form is constructed by appending 시 (si) if the stem ends in a vowel or 으시 (eusi) if the stem ends in a consonant:
|하다 (hada, "to do")||하시다 (hasida, "to do (by someone superior to the speaker)"|
|가다 (gada, "to go")||가시다 (gasida, "to go (by someone superior to the speaker)"|
|작다 (jakda, "(to be) small")||작으시다 (jag-eusida, "(for something superior to the speaker) to be small"|
