In German quiz shows (e.g., "Wer wird Millionär?"/"Who wants to be a millionaire?"), a contestant chooses between a set of possible answers, the choice is then locked and the answer checked. Before locking the board, the host typically asks the contestant (for example):
Soll Antwort C jetzt eingeloggt werden?
My question is the spelling of "einloggen".
einloggen, [...] besonders in Quizsendungen im Fernsehen, bei denen die Kandidaten jeweils aus mehreren Antworten diejenige auswählen müssen, [...]
and refers to
Herkunft englisch to log in
However, to me it seems that one would rather like to refer to the process of "locking" the board, which would point to the spelling "einlocken".
What is your take on this?
