What are the relative adverbs in English? They are; when, where and why. We use them as joiners to join clauses together. Each relative adverb has its own purpose or role and they are used to describe the noun in the clause.
We use the relative adverb ‘when‘ as an adverb in reference to time;
It wasn’t long ago when I used to go to the city centre.
It was two minutes ago I when I had been approached by the attendant.
I remember the time when I was younger and played football.
The relative adverb ‘where‘ is used as an adverb in reference to place;
I told the tourist where he needed to go to see the monument.
The islands where we met up with our friends were beautiful.
Jamie found a place where he could finally relax.
We use the relative adverb ‘why‘ as an adverb of reason;
We were told why they all had to leave so early last night.
I know exactly why Oliver has been acting so strangely.
Her constant excuses are the reason why she never managed to finish the project.
