this post gives a nice explanation about "is of"
A preposition phrase headed by of is a common way of attributing a quality to a noun, either as a modifier or as a predicate
and gives this example
This approach is of value. = This approach ‘possesses’ value, “it is valuable”.
follow this pattern
I am trying to understand this sentence
Acoustic absorption is of particular interest in soundproofing.
and got this
Acoustic absorption possesses particular interest in soundproofing.
which seems to be in a opposite order.
It is more reasonable to say soundproofing possesses interest in acoustic absorption.
what am I missing?
