Re: Adjectival or advirbial phrase
I will copy 5jj's comments here, because I completely agree with them as well:
However, the question and the responses made me think of a question I have posed before - "Does labelling matter?"
Labels such as 'adjectival/adverbial/participial phrase'
can be a useful shorthand when we are discussing how
the language works. However, I have found that some coursebooks appear to require students to label structures for the sole purpose of labelling. If the real objective is to enable learners to use
these labels in order to discuss how native speakers write and speak, then it can be useful. If it is simply an exercise in labelling language, then it is a waste of time.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
