It's such a joy to have "einem alten deutschen Kunden"...or, an old German client, with a familiar sense of humor. He used the word schleckerei last week, and we both knew what he meant without knowing the actual translation...lol
First I tried translating "sweet" to German on Google Translate:
As a NOUN:
As an ADJECTIVE--
...and SWEETS translates to Süßigkeiten....nope.
A neat thing about Google Translate is that it tries to translate as you add letters to the word; as I typed "s-c-h-l-e-c-" it asked if I mean SCHLECK"? which means Licking...lol...I was on the right track!
Schleck means licking
schlecke means lick
eating sweet things
Gawd, I'm learning German one odd word at a time...☺
