Questions & Answers about Hann sver að segja sannleikann.
Here að is the infinitive marker, so it works like English to in to tell.
- að segja = to say / to tell
- Hann sver að segja sannleikann = He swears to tell the truth
This is not the conjunction að meaning that. In this sentence, it introduces an infinitive verb.
Because segja is in the infinitive form.
After the infinitive marker að, Icelandic normally uses the infinitive:
- að segja = to tell
- segir = tells / is saying (finite, present tense)
So:
- hann segir = he says
- hann sver að segja = he swears to say / tell
Just like in English, He swears to tell..., not He swears tells...
