The usage of 'getreu' is from the sentence ''Wir halten es getreu dem Motto von Bruno Bettelheim''. I understand more or less what the sentence is saying, but I hadn't seen the word 'getreu' until that sentence, so I wanted to first make sure I was understanding its meaning correctly, and secondly find more example sentences that use the word in that context.
I'm strictly using an online dictionary to look-up words, and it doesn't seem to show what the abbreviations stand for. Sometimes I can find the abbreviation written out by using google, but other times there are just too many potential abbreviations, so I come here to check to see what a native speaker thinks it is given the context. Is there a way to find where an online dictionary lists its abbreviations? By the way, the online dictionary I have been using is http://de.thefreedictionary.com/
