you might not believe it but there is a
difference between the word in and in -
and when you use it the easiest way that
I remember it is that in is a static
word it indicates a position but it's
not moving whereas the word into is a
word that indicates movement or
something in motion so one way to think
about it is my blouse is tucked in
nothing's moving it's already tucked in
so we use the word I n but however if
I'm getting dressed and I'm actually
doing the action of tucking my blouse
into my skirt we use the word into to
indicate that motion is happening in the
middle of the sentence another way to
visualize this is to look at the pencils
on the desk I'd say that these pencils
are in the cup but now I'm going to put
this marker into the cup you can see
because I was performing an action
I used the word into so I hope that that
makes it a little clearer the difference
between in and in to
