Caelyn informs me that sprachtenntnisse means "language knowledge". Hell.

Und die Sprachkenntnisse der Verfasserin lassen manchmal ein wenig zu wünschen übrig: (Latein!). = And the language knowledge of the author leaves a little something to be desired. (Latin!)

Excuse me for having parents that made me take French, despite my pleas to take Latin instead. There's only so far you can go with an online Latin language dictionary, buckoes. ::wrinkles nose, determined not to let this bother her::
