I’m a lemon-scent polish you wipe with a rag;
A recruit that fraternity brothers might snag;
A donation you make for a PBS bag;
And an oath you recite to our national flag.

Who am I?

I’m the third piece in suits you remove when you’re hot;
To endow with a power, like tying the knot;
Keep your cards close to me, or they’ll see what you’ve got;
I’m flotation at sea; or protection when shot.

Who am I?

I’m a listening device that’s among a spy’s tricks;
I’m an insect you step on, like spiders or ticks;
I’m a glitch in the software you may need to fix;
And a yen for a hobby that fervently sticks.

Who am I?

I’m a summit for peace; group of teams who play ball;
Teacher meeting with parents; a multi-way call;
Presentation of papers to peers in a hall;
And engaging the press with your back to the wall.

Who am I?

From The Two Gentlemen of Verona:

This weak impress of love is as a figure
Trenched in ice, which with an hour’s heat
Dissolves to water and doth lose his form.

Shift around the letters, and it becomes:

I’m a spot in the stable where horses will stay;
A malfunction in engines that causes dismay;
I’m a space in the rest room; deliberate delay;
And a seat near the choir where clergy can pray.

Who am I?

I’m the wood of a trunk when you cut down a tree;
To accrue flying hours for pilots-to-be;
If your sleep has gone deep, then you’re sleeping like me;
And in natural states, I’ve a base set to e.

I am dragging your feet; I’m a step used in tap;
I’m to randomize cards; I’m a Super Bowl rap;
I’m the smallest of iPods; mix songs in the app;
And a daily routine for that Party Rock chap.

Who am I?

I’m the songs in a show; I help painters prosaic;
The mob’s betting racket; the fourth book Mosaic;
The terms’ coefficients in strings algebraic;
And Apple’s own app for all things formulaic.

Who am I?

I’m the stalk of the grass that the sugar men pick;
I’m an athlete from Raleigh who scores a hat trick;
I’m a Singapore sentence; a curved walking stick;
And a mint-flavored candy you’d get from St. Nick.

Who am I?
