I’m a warning that’s given so one may prepare;
I’m a sign that you post when you need to declare;
I’m to casually see, thus becoming aware;
And I’m word to your boss you’ll no longer be there.

Who am I?

I’m the royals that make up twelve cards in the deck;
I’m a book that’s online you might constantly check;
I’m the area found between hairline and neck;
And the nickname of Team member Templeton Peck.

Who am I?

I’m the angle that’s found in the joint of a square;
I’m the wing who’d have government stay laissez faire;
I’m correct on the facts; I’m the co-pilot’s chair;
And the speech that stays free or the arms you may bear.

Who am I?

I’m the ensemble cast of a musical play;
I’m a corporate structure, just like Fannie Mae;
I’m the guests you invite to a private soiree;
And a name that is used to imply CIA.

Who am I?

I’m a respite from work for some tea or a snack;
Take a shot at the cue ball to split up the rack;
I am taming a horse; I’m a bone with a crack;
And to add the last straw to a camel’s strained back.

Who am I?

I am having two fives and then taking an ace;
I’m a dose of a drug; I’m to get to first base;
A professional killing; to punch in the face;
And the song on the charts with a laudable place.

Who am I?

I can show you your seat, or stand watch at the door;
I once dated creation at four-thousand four;
I’m the groomsman at weddings who enters before;
And an R&B singer who did well with “More.”

Who am I?

I’m to misplace an object you never will find;
When the outcome of battle or sport is unkind;
When a doctor is leaving a patient behind;
Let your temper explode; or abandon your mind.

Who am I?

I’m a sad variation of musical scale;
I’m a lesser-known league; unimportant detail;
I’m a petty offense that will mean little jail;
And a child restricted from drinking brown ale.

Who am I?

UPDATE: Riddle solved by Daweesa. See comments for answer.

I’m the dollar that makes all your bang somewhat cheap;
I’m the male of the deer and the goat and the sheep;
Help a rider dislodge with a quick sudden leap;
And the onerous blame that you pass or you keep.

Who am I?
