Binding: When seg, seg selv, sin and ham Are Required

When does a sentence force the reflexive seg and when must it use the ordinary pronoun ham? When is the possessive sin required and hans forbidden? These choices are not free — they are governed by binding, the grammar of which noun a pronoun-like word may "point back to." English speakers find this hard because English -self is more permissive and English his doesn't track the subject. Norwegian, by contrast, has a tightly engineered system: reflexives are subject-oriented, mostly local, but — and this is the celebrated part — Norwegian allows a reflexive to reach across a non-finite clause to a higher subject in a way English flatly cannot. This page is the deep dive. (For the everyday sin vs hans/hennes contrast, start with sin vs hans/hennes; here we go to the bottom of it.)

The two principles in plain terms

Binding theory boils down to two complementary rules. Stated without jargon:

• Reflexives (seg, seg selv, sin) must find their antecedent inside their own local domain — roughly, the nearest subject. They are "needy": they require a buddy close by, and that buddy must be the subject.
• Plain pronouns (ham, han, hans, hennes) must be free in that same local domain — they must not point to the local subject. They look outside for their antecedent (or to nobody in particular).

This produces a near-perfect division of labour: where a reflexive is required, a pronoun is barred, and vice versa. The single most useful instinct: if the thing being referred to is the subject of the same little clause, use the reflexive; if it's someone else, use the pronoun.

That contrast — seg for "himself," ham for "him (someone else)" — is the whole engine in miniature. Two words, two readings, zero overlap.

seg selv: locally bound, subject-oriented

The strong reflexive seg selv "himself/herself/itself" is the most tightly bound element. It must be bound by the subject of its own clause — it cannot reach up, and it cannot take a non-subject as antecedent.

Look hard at the third example. In English, "Jon told Per about himself" is ambiguous — himself could be Jon or Per. In Norwegian, seg selv is subject-oriented, so it can only be Jon. To get the "about Per" reading you must switch to ham: Jon fortalte Per om ham (with ham = Per, the non-subject). This is the single most counter-intuitive thing for English speakers: Norwegian reflexives ignore objects as potential antecedents.

Why seg selv and not bare seg? Adding selv forces the coreferential reading and is obligatory when the reflexive is a true co-argument of the verb that contrasts with the subject as a separate participant — e.g. like "like," hate "hate," se "see (in the mirror)." With inherently reflexive verbs (vaske seg, skynde seg, sette seg) bare seg is enough, because there's no "someone else" reading to rule out. (More in reflexive seg.)

sin vs hans/hennes: the subject-bound possessive

The possessive splits the same way. Sin/sitt/sine is the reflexive possessive: it must refer to the subject of its clause. Hans/hennes is the free possessive: it must refer to someone other than that subject.

This is a distinction English simply lacks. English "Jon drove his car" leaves it open whose car it is; Norwegian forces you to decide and mark it. The agreement of sin/sitt/sine tracks the possessed noun, not the possessor — bilen sin (masc.), huset sitt (neut.), barna sine (plur.) — which is itself a trap, because the natural English instinct is to make the possessive agree with the owner ("his/her"). It does not: Kari kjørte bilen sin and Jon kjørte bilen sin use the identical sin, because sin agrees with bilen, not with Kari or Jon.

A crucial limit: sin is clause-bound and subject-bound. It cannot refer to an object, and it cannot be the possessor of the subject. So Jon in subject position licenses sin, but you cannot say ✱Jon sin bror kom meaning "Jon's brother came" in standard Bokmål writing (the garpegenitiv Jon sin bror exists in speech and dialect — (regional/colloquial) — but it's a different construction). In the bound use, the antecedent of sin is always the subject.

The celebrated long-distance seg

Now the famous part — the feature linguists cite Scandinavian for. A bare reflexive seg (without selv) can be bound by a higher subject across a non-finite (infinitival) clause boundary. English -self cannot do this at all.

In Jon ba oss snakke pent om seg, the reflexive seg skips right past the nearer subject oss "us" and binds to Jon, the subject of the main clause. That is the long-distance reflexive. Two conditions make it possible:

1. The intervening clause is non-finite (an infinitive, å snakke, with no tense of its own). Across a finite clause — one with a tensed verb — seg can no longer reach up.
2. seg is subject-oriented as always, so it bypasses the object oss and locks onto the higher subject.

Compare what happens when the lower clause is finite:

The first shows the locality wall: with finite at Per vasket seg, seg can only mean Per, the nearest subject — it cannot climb to Jon. To point back to Jon across that finite boundary, Norwegian switches to the pronoun ham, exactly as in the second example. So the boundary type — finite vs non-finite — is the master switch: non-finite lets seg reach up; finite walls it off and hands the job to ham/hans.

This is the property English lacks entirely. "Jon asked us to speak nicely about himself" is, for most English speakers, ungrammatical or strained — English himself wants a local antecedent (us), can't find a matching one, and the sentence breaks. Norwegian repairs the same meaning with effortless long-distance seg. Among the world's languages this kind of subject-oriented long-distance reflexive is a genuine areal hallmark of the Scandinavian family, and it's worth savouring.

Putting it together: a decision procedure

Faced with "is it seg(selv), sin, or ham/hans?", run this:

1. Does it refer to the subject of its own clause? If yes → reflexive. Co-argument that needs disambiguating from the subject → seg selv; inherently reflexive verb → bare seg; possessive → sin/sitt/sine.
2. Does it refer to a higher subject, across a non-finite clause? If yes → long-distance bare seg (or sin for the possessive).
3. Does it refer to an object, or across a finite clause, or to someone outside the sentence? → plain pronoun ham/han/hans/hennes.

These two say the same thing but route through different grammar: the infinitival undersøke seg allows long-distance seg; the finite at han skulle undersøke henne blocks it and forces henne.

Common Mistakes

1. Letting a reflexive point to an object. English "Jon told Per about himself" is ambiguous; Norwegian seg selv is subject-oriented and can only be Jon.

2. Using hans/hennes where sin is required. When the possessor is the subject, Norwegian demands sin; hans would mean someone else's.

3. Agreeing sin with the owner instead of the possessed noun. sin/sitt/sine tracks the possessed noun's gender and number.

4. Avoiding the long-distance seg and over-using a pronoun. Across a non-finite clause, seg is the natural choice; defaulting to ham loses the "him = the matrix subject" reading.

5. Trying to send seg across a finite clause. Once there's an at + tensed verb, seg is trapped locally; use ham/hans to refer up.

Key Takeaways

• Reflexives (seg, seg selv, sin) bind to the subject of their local clause; pronouns (ham, hans, hennes) must be disjoint from that subject.
• seg selv is subject-oriented — it never takes an object as antecedent (unlike English -self).
• sin/sitt/sine = the subject's; hans/hennes = someone else's. sin agrees with the possessed noun, not the owner.
• Long-distance seg crosses a non-finite clause to bind a higher subject (Jon ba oss hjelpe seg = help Jon) — a hallmark Scandinavian feature English lacks.
• A finite (at
  • tensed) clause walls reflexives off; to refer to a higher subject across it, use ham/hans.
