pre-head modifier и attributive modifier как это переводится?

Sridhar Ramesh writes to me to point out that "were it not for Wikipedia, many
of us would have difficulty appreciating even the title "Strictly Ballroom" as strictly grammatical." It is an excellent point. Why is strictly here allowed as (apparently) a pre-head modifier of a noun, ballroom? Because it really means strictly ballroom dancing, i.e., falling within the strict definition of the special kinds of dancing known as ballroom dancing. The adverb modifies an attributive modifier (ballroom) of a noun (dancing, derived from a gerund-participle of a verb) that has been omitted. This is indeed a difficult phrase to analyse. Maybe I'm not so dumb to have had trouble with it.
