the preposition

Mollie walked into her aunt’s house. (Into connects walked and house.)
My mom exercises quietly in the morning. (In connects the idea of
exercises and morning.)

The professor placed the book underneath the large desk. (Underneath
connects the idea of placed and desk.)

Note: To remember many of the one-word prepositions listed in the following
box, remember the sentence, ‘‘The plane flew ..............the clouds.’’
Any word that can be logically placed into that blank is a preposition. Then
simply memorize those few that do not work in that sentence (aboard, as,
but, concerning, despite, during, except, like, of , out, since, till, until, with, and
without), and you will know your prepositions!
