This is the 1694th most frequent German word.
daran
"Daran" means "on it," "about it," or "at it," referring to something mentioned or implied.
In this sentence, 'daran' connects the verb 'denken' (to think) to an implied subject or object, generally understood as 'about it'.
Er denkt oft daran.
He often thinks about it.
Here, 'daran' works as a reference object for the verb phrase 'sich gewöhnen', indicating the action of getting accustomed to something.
Sie haben sich daran gewöhnt.
They have gotten used to it.
In this example, 'daran' links to the verb 'teilnehmen' (to participate), specifying the event or action being participated in.
