Questions & Answers about Ég held að íslenskan sé erfið, en það er gaman.
Að is the conjunction that, used to introduce a subordinate clause after verbs like halda (to think / believe), segja (to say), vita (to know), etc.
So the structure is basically: Ég held [að + clause].
Sé is the present subjunctive form of vera (to be). Icelandic often uses the subjunctive after að with verbs of opinion/reporting like Ég held..., especially when the statement is framed as a thought, claim, or subjective assessment rather than a plain fact.
You may also see Ég held að íslenskan er erfið, using the indicative er, which can sound more like you’re stating it as a straightforward fact. The subjunctive (sé) is very common and often feels more natural in careful standard Icelandic in this pattern.
Held is the 1st person singular present tense of halda (to hold, and also to think/believe in this construction).
- infinitive: að halda
- present (ég): ég held
So ég held = I think / I believe (in this usage).
