voru
"Voru" is the third person plural past tense of the verb "vera," meaning "were" in English.
In this sentence, 'voru' serves as a past tense auxiliary verb indicating the continuous action of learning in the past.
Þau voru að læra nýtt tungumál.
They were learning a new language.
Here, 'voru' is again a past tense auxiliary verb used to denote a continuous action, in this case, waiting, which occurred in the past.
Foreldrarnir voru að bíða eftir börnunum.
The parents were waiting for the children.
In this example, 'voru' functions as the main verb in the past tense, describing the state or condition of the friends being at the celebration.
