leiðast is the everyday Icelandic verb for being bored — but it is built on a structure that has no parallel in English, and getting it right means unlearning two instincts at once. First, the bored person is not the subject in the way English makes them: the experiencer goes in the dative (mér leiðist, literally "to-me is-tedious"), never the nominative. Second, leiðast is a middle-voice (-st) verb, the deponent middle of the active leiða "to lead" — so the -st is baked into the lexical form and never comes off. Add to that the orthography (it is leiðast, with ð, not leidast) and you have a verb that English speakers reliably mangle in three different ways. This page lays out the paradigm, the dative-experiencer syntax, the nominative-theme agreement, and the single most useful distinction in the whole entry: mér leiðist ("I'm bored") is not ég er leiður ("I'm sad").
Conjugation
Class: weak middle-voice (miðmynd), used with a dative experiencer and an optional nominative theme. Like its dative-subject cousins finnast, líka, and þykja, the verb is almost always 3rd person and agrees with the nominative theme, not with the dative experiencer: a singular theme (or no theme) takes leiðist, a plural theme takes leiðast. Experiencer: dative (mér, þér, honum, henni, okkur, ykkur, þeim). Auxiliary: hafa — mér hefur leiðst "I have been bored."
| Principal parts | |
|---|---|
| Infinitive | að leiðast |
| 3sg present | leiðist |
| 3sg past | leiddist |
| Supine | leiðst |
Agreement runs off the nominative theme. With no theme, or a singular theme, the verb is leiðist / leiddist; with a plural theme it is leiðast / leiddust. The dative experiencer (mér, þér, honum …) stays constant and never triggers agreement:
| Theme | Present (nútíð) | Past (þátíð) |
|---|---|---|
| no theme / singular theme (e.g. fundurinn) | leiðist — mér leiðist "I'm bored" | leiddist — mér leiddist "I was bored" |
| plural theme (e.g. fundir) | leiðast — mér leiðast fundir | leiddust — mér leiddust fundirnir |
| Theme | Present subjunctive | Past subjunctive |
|---|---|---|
| singular / no theme | leiðist | leiddist |
| plural | leiðist | leiddust |
| Non-finite & related forms | |
|---|---|
| Imperative | — (none; you can't command boredom) |
| Supine | leiðst — mér hefur leiðst "I have been bored" |
| Active counterpart | leiða "to lead, to guide" (a separate, ordinary verb) |
Note the spelling at every step: present leiðist and infinitive leiðast keep the single ð; the past leiddist doubles the d (the weak -d- preterite marker lands next to the stem's ð, which is then written dd). The supine leiðst drops the vowel. Mind the ð — leidast with a plain d is simply a misspelling of a different shape.
The dative experiencer: mér leiðist
Like finnast, líka, þykja, leiðast puts the person who feels bored in the dative: mér leiðist, þér leiðist, honum leiðist, henni leiðist, okkur leiðist, þeim leiðist. The logic is the one shared by the whole dative-subject family: the experiencer does not do anything, so they are not an agent-subject in the nominative — boredom is something that happens to them, and Icelandic codes that "to whom" relation with the dative. The most stripped-down form has no theme at all: just dative experiencer plus leiðist, which alone means "X is bored."
Mér leiðist.
I'm bored. — the whole sentence: dative experiencer mér + leiðist, no theme. Literally 'to-me is-tedious'.
Krakkarnir kvarta yfir því að þeim leiðist í bílnum.
The kids complain that they're bored in the car. — dative þeim + leiðist; 'they're bored' with no nominative subject at all.
Honum leiddist svo mikið í tímanum að hann sofnaði.
He was so bored in class that he fell asleep. — past leiddist, dative honum; boredom as something that befell him.
The nominative theme triggers agreement
leiðast can take a nominative theme — the thing you find boring or tedious — and that theme behaves exactly like the theme of finnast and þykja: it is nominative and it controls the verb's number. A singular theme keeps leiðist; a plural theme forces leiðast (present) or leiddust (past). This is the half of the construction English speakers most often get backwards, because in English "I find meetings boring" makes I the subject and meetings the object — in Icelandic it is the reverse, structurally: mér is dative, fundir is the nominative subject driving agreement.
Mér leiðast fundir.
I find meetings boring. — plural theme fundir is nominative and forces the plural verb leiðast; the dative mér is unchanged. (NOT *mér leiðist fundir.)
Henni leiðist þessi mynd alveg rosalega.
She finds this film incredibly boring. — singular theme þessi mynd keeps leiðist; dative experiencer henni.
Mér leiddust öll þessi löngu erindi á ráðstefnunni.
I found all those long talks at the conference boring. — past plural theme erindi → leiddust; the dative mér doesn't agree.
leiðast (be bored) vs leiða (lead): the same root, two verbs
leiðast is the middle voice of the active verb leiða "to lead, to guide, to take by the hand" — and the two have drifted to entirely different meanings, as middle-voice verbs so often do. The active leiða is a perfectly ordinary nominative-subject transitive: hún leiðir hópinn "she leads the group." Strip a sentence of its dative and you do not get a grammatical "active" version of leiðast — you get the unrelated leiða. So leiðast is what grammarians call a deponent: it exists only in the middle voice for the "bored" meaning, and the -st is not removable.
Hún leiðir gönguhópinn upp á fjallið.
She leads the hiking group up the mountain. — active leiða, ordinary nominative subject hún + accusative object; nothing to do with boredom.
Mér leiðist að bíða, en honum leiðist það ekki neitt.
I find waiting boring, but he doesn't mind it at all. — leiðast with an infinitival theme 'að bíða'; dative experiencers mér / honum.
There is also a third, idiomatic use worth knowing: with the preposition á + accusative, the reciprocal-flavoured leiðast means "to walk hand in hand, arm in arm" (literally "lead each other") — þau leiddust eftir ströndinni "they walked hand in hand along the beach." That sense does have a nominative subject and is the original "lead" meaning surviving in the middle voice. Context separates it cleanly from "be bored," which always has a dative experiencer.
Gömlu hjónin leiddust niður götuna.
The old couple walked arm in arm down the street. — the reciprocal 'lead each other' sense of leiðast, with a nominative subject (gömlu hjónin), NOT the bored sense.
mér leiðist ≠ ég er leiður: 'bored' vs 'sad'
This is the single most important line in the entry, because the trap is laid by the adjective leiður itself. mér leiðist = "I'm bored / I find it tedious" — an experience of boredom, with the dative experiencer. But ég er leiður = "I'm sad / sorry / fed up" — a nominative subject plus the adjective leiður, which in modern Icelandic means unhappy, not bored. They share the root leið- and look like they should be paraphrases of each other, but they are not: one is boredom, the other is sadness, and the grammar (dative + verb vs nominative + adjective) tracks the meaning exactly.
Mér leiðist heima ein á kvöldin.
I get bored at home alone in the evenings. — boredom: dative mér + leiðist.
Ég er leiður yfir þessu, þetta var ekki meiningin.
I'm sad / sorry about this, that wasn't the intention. — sadness/regret: nominative ég + adjective leiður (masc.); leið (fem.), leitt (neut.).
So an English "I'm bored" must become mér leiðist, with a dative — and an English "I'm sad" must become ég er leiður/leið, with a nominative and an agreeing adjective. Reaching for ég er leiður to mean "I'm bored" is one of the most common — and most invisible — errors a learner makes, because it is grammatical Icelandic that simply means the wrong thing.
Common Mistakes
❌ Ég leiðist í vinnunni.
Case error — the experiencer is a DATIVE experiencer, not a nominative subject. It's mér leiðist, never ég leiðist.
✅ Mér leiðist í vinnunni.
I'm bored at work.
The headline error, transferred straight from the English subject "I." leiðast never takes a nominative ég; the bored person is dative mér.
❌ Ég er leiður á fundinum.
Wrong word — 'I'm bored' is the dative-experiencer mér leiðist; ég er leiður means 'I'm SAD/fed up', not 'bored'.
✅ Mér leiðist á fundinum.
I'm bored in the meeting.
leiður the adjective is "sad," not "bored." For boredom you need the dative-subject verb, not the nominative-plus-adjective construction.
❌ Mér leiðist fundir.
Agreement error — the verb agrees with the nominative theme, and 'fundir' is plural, so it must be mér leiðast fundir.
✅ Mér leiðast fundir.
I find meetings boring.
The dative experiencer doesn't control agreement; the nominative theme does. A plural theme needs the plural leiðast / leiddust.
❌ Mér leiðir í bílnum.
Wrong verb — you've used the active 'leiða' (to lead). 'Be bored' is the middle voice leiðast: mér leiðist í bílnum.
✅ Mér leiðist í bílnum.
I'm bored in the car.
You cannot strip the -st off to make an "active" version. Bare leiða means "to lead," a different verb; the bored sense lives only in the middle voice leiðast.
❌ Mér leidist heima.
Spelling error — it's leiðist, with ð, not 'leidist' with a plain d. The ð is not optional.
✅ Mér leiðist heima.
I'm bored at home.
The ð is part of the stem (leið-) and must be written. leidist is not a lighter spelling of the same word — it is simply wrong.
Key Takeaways
- leiðast ("to be bored / find tedious") is a dative-subject middle-voice verb: present leiðist, past leiddist, past subjunctive leiddist, supine leiðst. No imperative.
- The bored person is dative (mér leiðist, "I'm bored"), never nominative — there is no ég leiðist.
- A nominative theme controls agreement: singular leiðist, plural leiðast / leiddust (mér leiðast fundir, "I find meetings boring").
- It is the middle voice of leiða "to lead"; the -st is lexical and never removable. Bare leiða = "lead," a separate verb. (The reciprocal leiðast "walk hand in hand" keeps a nominative subject.)
- mér leiðist ("I'm bored") ≠ ég er leiður ("I'm sad"): the dative-verb construction is boredom, the nominative-adjective construction is sadness. Don't swap them.
- Mind the ð: leiðist / leiðast / leiddist, never leidist.

- finnast vs þykja vs halda: 'Think/Seem'B1 — The 'think/seem/find' cluster that English collapses into one word: finnast (dative subject, a subjective impression — mér finnst þetta gott), þykja (dative subject, more formal and evaluative — mér þykir vænt um þig), and halda (ordinary nominative subject, a belief or conjecture — ég held að…). The case of the subject is the giveaway: an impression takes mér; a belief takes ég.
