There is but one suffix in this category. It is used to express extreme politeness or deference. It is used only in addressing a superior, someone of higher rank in the Klingon social, political, or military hierarchy. It is never required.
qaleghneS I am honored to see you (legh see)
HIja'neS do me the honor of telling me (ja' tell)
This suffix is used rather infrequently by Klingons.
