Very generally speaking, coordination occurs when two or more parts of sentences that have equal weight and "independence" are linked by various means – sometimes in syndeton with coordinating words (typically conjunctions), sometimes in asyndeton, or just lined up in sequence. Nouns, for instance, syndetically:
"The roadies got the rabies and the scabies and the flu"
"Love is like birth and death and taxes";
or asyndetically: "curiosity, tenderness, kindness, ecstasy"
Or noun phrases: "Raindrops on roses and whiskers on kittens"
"The red in your lips, the gold in your hair, the blue in your eyes"
Coordination of clauses is an important feature of English sentence structure. Typical is the syndetic linking of one independent clause to another with a conjunction:
"My name is Rick Perry, and I approve this message."
"You say either and I say either."
"Outside of a dog, a book is man's best friend; and inside of a dog, it's too dark to read."
"I love you, but I can't live with you, so I'm leaving."
Coordination of clauses can also be asyndetic:
"The night is young, the skies are clear, so if you want to go walking, dear, it's delightful, it's delicious, it's de-lovely."
Very often, coordination involves ellipses – leaving elements out. One subject can share several coordinated verbs:
"I washed the dog, fed the cat, and mopped the floor."
"They sit at the bar and put bread in my jar and say Man, what are you doing here."
Or verbs can disappear in "gapping":
"He couldn't hit a fastball, a curveball, or a fifteen-foot jump shot."
Gapping is a feature of much of the poetry in the English Bible, as in Psalm 114.
