Follow up to this post. I became interested in the title of this question, when the following exercise came in workbook:
Rearrange the following and form a sentence:
besonders-die Sommermonate der Jahre 1350 bis 1370 extrem regenreich- sein - während dieser Zeitspanne-in, Deutschland- die meisten Menschen- der Pest- erliegen
When I made the sentence, I treated the besonders like an adverb and did something like so:
besonders war die Sommermonate...
but according the solution manual, I should have used it instead as an adjective,
Besonders die Sommermonate der Jahre 1350 bis 1370 waren...
What is the difference in meaning between these two usages? Is there something general that we can say about words the meaning difference of words which double adjective and adverbs when they are use as adverb vs adjectives?
