Informal Structures Using Prepositions With Adjective Clauses
In spoken or less-formal English, prepositions such as at, in, about, etc., which are usually connected to a verb or an adjective, go at the end of Adjective Clauses.
- The waiter who we were talking about actually came in to deliver our food five minutes ago.
- We bought our snacks at the store which we bought our groceries at.
Replacement Of the Relative Clause
We can also replace some relative clauses with an infinitive clause. This happens after ordinal numbers, superlatives and sequencing adverbs like next, last, and only.
- She was the second person in her family to become vegan. (She was the second person in her family who became vegan)
- Meditation is one of the oldest forms of exercise to be practiced. (Meditation is one of the oldest forms of exercise which is practiced.)
- The last doctor to see him was a specialist. (The last doctor who saw him was a specialist)
This structure is used more commonly with defining adjective clauses, which you will look at more closely in Grammar 9-3.
