óþarft
þarft is the second-person singular present indicative form of the Icelandic verb þurfa, meaning “to need.” It is used when the subject is the person addressed, typically expressed as “þú þarft.” The form corresponds to the subject you in sentences such as “Þú þarft að fara” (You need to go / You have to go). In Icelandic, the infinitive is introduced with the particle að, so constructions with sentir: “þarft að” followed by a verb in its infinitive.

Form and pronunciation: þarft forms from the verb þurfa. The initial letter þ is a voiceless dental
