Hi, I'm Phil, and I'm going to tell you the
difference between 'beside' and 'besides'.
And it's one small letter, but it's quite a big difference.
'Beside' (with no 's') is a preposition, and
we usually use it to talk about physical position.
So, you can say: 'Put the chair beside the table.'
Or: 'Come and sit beside me.'
It's like a more formal version of 'next to'
Now, 'besides' (with an s) is either a preposition
or an adverb, and is often used to add information.
'Besides knowing grammar well, you need to
have a good vocabulary.'
'You should do something else besides studying.'
Here it's like 'as well as'
As an adverb, it's often used to add a more
important or stronger point.
'I'm going to practise now because I've got
time and besides, I need to!'
It's like a less-formal version of 'moreover'
So, besides remembering that 'beside' is for
physical position, remember that 'besides' is
for adding information.
