Idioms beginning with I

In the blink of an eye

In the same vein

In the heat of the moment

In the line of fire

In the lap of luxury

In one’s element

In for the long haul

In for a penny, in for a pound

In like Flynn

If worse comes to worst

If looks could kill

Idle hands are the devil’s workshop

Icing on the cake

If all else fails

If you play with fire, you get burned

If the going gets tough, the tough get going

If push comes to shove

If it ain’t broke, don’t fix it

If the cap fits, wear it

I’ve got a bone to pick with you

It’s raining cats and dogs

It’s not over until the fat lady sings

It’s a small world

It takes one to know one

It takes two to tango

It takes all sorts

It never rains but it pours

In with the old, out with the new

In with a chance

In vogue

In vain

In two minds

In tune with something

In touch

In the works

In the way

In the wake of something

In the throes of something

In the teeth of something

In the spotlight

In the seventh heaven

In the same league

In the same breath

In the same boat

In the public eye

In the pipeline

In the offing

In the nick of time

In the main

In the loop

In the long run

In the flesh

In the firing line

In the face of something

In the event of something

In the end

In the driver’s seat

In the clear

In the cards

In the blood

In the blink of an eye

In the bag

In the balance

In the air

In store

In stitches

In someone’s shoes

In someone’s good books

In someone’s bad books

In short

In retrospect

In question

In print

In practice

In pieces

In part

In over one’s head

In order

In one’s sights

In one’s shoes

In one’s own words

In one’s own right

In one’s good books

In one’s element

In no time

In my book

In moderation

In lieu of something

In light of something

In keeping with something

In high spirits

In due course

In dire straits

In deep water

In cold blood

In black and white

In a word

In a rut

In a tight spot

In a pickle

In a nutshell

In a fix

If worst comes to worst

If you scratch my back, I’ll scratch yours

If you can’t beat them, join them

If wishes were horses

If the shoe fits
