Hi! Are the underlined subordinate clauses? Thanks, Fulvio

1. If you study, I'll buy you a bicycle.

2. If you are going to study, I'll buy a bicycle.

Traditional grammar analyses this "if" as a subordinating conjunction that introduces conditional clauses.

But modern grammar analyses it as a conditional preposition, so the underlined elements are not clauses but preposition phrases.

I much prefer the modern analysis. See this up-to-date dictionary:
