I have come across some sentences and sometimes I wonder whether the preposition at the end of the sentences
are necessary [not those in relative clause like "This is the bag which I put my purse into"].
E.g. Furniture is an uncountable noun as far as I'm aware (of). I have heard some native speakers use of and some drop it.
There are lots of activities for you to participate in. This 'in' is kind of necessary, right? Since you participate IN activities.
Any rules or suggestions how can I be certain when these prepositions are optional and when they are obligatory>?
thank you so much
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Many natives do say things like "Where are you at?" and "Where are you going to?" In those cases, the ending preposition is not necessary.
