Meaning of に in 本当に


In the sentence これは[本当]{ほんと}に[高]{たか}いです, meaning " _This is really expensive_
", I'm having trouble understanding the meaning of に, which usually has some
connotation of "to", "on", or "at".

This is a phrase presented in Memrise Japanese Level 3, and I'm trying to
start understanding the grammatical sense of the phrases.




Adjectives can often be used 'adverbially' (though they are generally not
analysed by Japanese grammarians as 副詞) by adding に rather than な or in this
case の.
