Words That Travel in Pairs, Words That Flip
Binomials and prefix word formation — both drawn from the story
Two patterns in this lesson — both drawn from the story you just read.
First, some English expressions always travel in pairs — sink or swim, mix and match, hide and seek. These are called binomials. The order is fixed. You can never say seek and hide.
Second, English flips the meaning of a word by attaching a small piece to the front — happy → unhappy, fortune → misfortune. That small piece is called a prefix. Both patterns reward you for noticing once and then reusing forever.
Binomials — words that always travel together
Eight binomials from Kaveri's exercise. Tap each card to flip.
Q1.Which sentence uses part and parcel correctly?
Prefixes — small flips with big effects
Six prefix forms from Kaveri's exercise. Each card shows the root, the prefix that fits, and the new word.
Q1.Which prefix correctly makes the opposite of fortune?
One quick application.
Open prompt: Use the binomial sink or swim in a sentence of your own. (Try it in your head, then tap to see two model sentences.)
