"His mother was a strange, fey woman"
Hey there,
Acrid, piercing, acute, and keen are all synonyms of the word pungent. The word pungent id an adjective and based on my research, this word means "having a sharp and strong taste of smell".
~Jurgen
I think its D.infintive ..........hop this helps
"An" is one of two indefinite articles.
There are some words that have the meaning of "fond of being with others", for example sociable, gregarious, etc.
Hope this helps~
