Relative, Not Absolute: Keigo Shifts with Audience

There is a hidden assumption English speakers carry into keigo: that some people simply rank higher, and higher-ranked people get more deference, full stop. Under that assumption you would expect a fixed table — the principal always gets sonkeigo, my father is my father — and you would apply it no matter who you were talking to. Modern Japanese breaks that assumption at the root. It runs on 相対敬語（そうたいけいご, relative honorification): elevation is computed from your current relationship and audience, not from the referent's absolute status. There is no permanent "this person always gets sonkeigo" rule in daily life. Change the listener, and the very same person flips from elevated to humbled.

相対 vs 絶対: two ways a language can honor

The opposite system is 絶対敬語（ぜったいけいご, absolute honorification): a high-status figure is elevated always, by everyone, regardless of who is speaking or listening. Classical Japanese worked this way for the Emperor — the throne was elevated in every mouth. But everyday modern Japanese abandoned that model for the relative one, and the consequence is profound:

Under 相対敬語, keigo does not encode how important a person is. It encodes where that person stands relative to you and your listener, at this moment.

So keigo competence is not really a vocabulary problem. The special verbs (いらっしゃる, 申す, 伺う…) are a finite list you can memorize in a week. The hard, career-long skill is recomputing the audience — redrawing the うち／そと line every time the listener changes and re-deciding who rises and who falls.

The demonstration: one principal, two audiences

Watch a single person — a school principal (校長) — described by the same teacher to two different listeners.

Speaking to students, the teacher and students are on one side and the principal stands above them; he is elevated:

おっしゃる lifts the principal's speaking. Now the same teacher reports to the Board of Education — an outside body over the whole school. The line has been redrawn above the principal: relative to the Board, the principal is now the teacher's own うち, the humble side. The same words about the same man invert:

The honorific 先生 dropped, おっしゃる became humble 申す, and the principal — untouched, unaware, unchanged — went from elevated to lowered by nothing but a change of listener. This is 相対敬語 in one breath: the referent held still; the audience moved; the keigo followed the audience.

Even your own father slides

Family makes the relativity vivid, because your father's rank to you never changes — yet how you speak of him does. To an outsider, your father is deep うち and gets humbled:

But to your younger sibling, inside the family, your father stands above you both, and casual elevation is perfectly natural:

Same father, same event — 父…おります to the outsider, お父さん…帰ってきてない to the sibling. If honorification were absolute, this would be impossible; because it is relative, it is obligatory. (Note that even the word for "father" shifts: humble 父 outward, warm お父さん inward.)

How this differs from your source language

Korean is the sharp contrast, and worth naming because it is so close geographically yet chose the other model. Korean honorifics lean absolute: a boss or a grandfather is typically kept elevated regardless of who is listening. A Korean employee, asked by a customer whether the boss is in, will normally still honor the boss ("the president is not in," with the honorific verb). Do that word-for-word in Japanese — elevate your own president to a customer — and you have made the classic error the relative system forbids. (Korean does have a traditional in-family exception, 압존법, where a middle-ranking elder is not elevated before a higher one, but modern standard usage has been softening even that toward the absolute.) The takeaway: do not import Korean's "once elevated, always elevated" instinct into Japanese.

European T/V (French tu/vous, German du/Sie, Spanish tú/usted) is a different beast entirely. T/V chooses formality toward the person you are speaking to, fixed by your relationship with them — it is essentially the 丁寧語 axis, the listener dial. It does not re-rank a third person you describe based on your audience. Japanese's relative behavior lives on the referent axis, which T/V languages have no equivalent of at all. So if your instinct comes from French or German, the piece you are missing is precisely the one that shifts: honorification of the person described.

An honest caveat: a pocket of 絶対敬語 survives

It would be tidy to say "modern Japanese is purely relative," but that overstates it. Genuine 絶対敬語 survives in a few registers — most notably around the Imperial Household, where the Emperor and Empress are elevated in the news and in official speech no matter the speaker, and to a lesser degree in certain historical, religious, and highly ceremonial contexts. These are marked exceptions, not the daily norm. For ordinary work, family, and social life, assume the relative system; just do not be surprised when NHK elevates the Emperor in a sentence where relativity alone would not require it.

Common mistakes

Mistake 1 — Treating a title as a permanent elevation trigger. "Once a 先生/校長/部長, always sonkeigo," applied even toward outsiders above them.

Mistake 2 — Elevating your own father to an outsider. Because his rank to you feels fixed, learners keep the honorific outward.

Mistake 3 — Importing absolute honorifics from Korean (or fixed-status thinking). Keeping your boss elevated to a client the way an absolute system would.

Mistake 4 — Forgetting to recompute when the listener changes. Using one fixed register for a person across a whole day regardless of who joins the conversation.

Key takeaways

• Modern daily Japanese is 相対敬語（relative): elevation depends on the current audience, not the referent's fixed status.
• The same sentence about the same person can be respectful or rude depending only on who is listening.
• Your boss, teacher, even your father flip from elevated (to insiders) to humbled (to outsiders).
• Korean leans absolute (keep the boss elevated to anyone); European T/V is only the listener axis — Japanese's shifting part is the referent axis neither replicates.
• A pocket of 絶対敬語 survives (the Imperial Household, ceremony), but assume the relative system for ordinary life.
