Wir dachten daran hinzugehen, entschieden uns aber letzen Endes dagegen.

[zzcguns]

English Translation

We considered going, but finally decided against it.

The cloze word in this sentence is letzen. This word appears to be incorrect and should be letzten, i.e. there should be a “t” after the “z”. This was changed on Tatoeba some time ago.

I’ve reported this using the little red flag.

You are right, this is definitely a typo. ‘letzten’ would be correct.
