the first sentence is :
(The first road constructed was the Appian way,which led,from Rome to Brundisium ,a port in what is now southern Italy.)
I want to know why we use in what.I don't see what in adj clause.don't you thing we should use in which insteas of in what and overall do you think that sentence is right or not??
the second sentence is:
(Techniques included preparation of foundation soils and base courses ,brick paving ,and,most importantly ,provision of adequate drainage.)
i want to know the grammatical point about using most importantly.for example why don't we use the most important or most important instead.
"In what" is correct. The port is in what is now Italy. It is not in "which" is now Italy.
Think of "what is now southern Italy" as one thing. It is a phrase that is acting as the object of the preposition "in." The sentence could say "a port in Italy." The grammar is the same. Instead of "Italy" as the object, the object of "in" is "what is now southern Italy."
