a book
a pen
a phone
a lot
a little
a day
an apple
an egg
an hour
an idea
at last
after you
after all
and then
and you
be late
be cool
be friend
be quiet
be free
can not
come in 
come on
come out
come back
come up
come over
come here
come down
cool down
cool off
cool man
cut out
cut off
cut down
check in
check out
carry on
do it
do not
each one
each day
each time
each year
even so
even as
even now
even more
even if
for you
for me
for sure
for what
far from
far away
far cry
go to
go on
go out
go easy
go away
go back
good day
good luck
good job
good idea
got it
how long
how many
how much
how come
hold on
hold back
hurry up
have fun
have to
