VERBS OF SENSATION.  The basic verbs of sensation are see, hear, feel, smell, and taste.  For any particular passage involving a character's perception of the senses, fiction-writers face the choice of whether or not to actually utilize the applicable verb of sensation. 

Example using verbs of sensation (in italics):

• Cisco paused at the back door of the livery stable.  He smelled a mixture of prairie hay and manure.  He could see horse stalls to his right and rows of saddle racks to the left.  He heard a horse whinny and stomp its hooves. 

As explained by Evan Marshall, in The Marshall Plan for Getting Published, "Though it's desirable to make use of your character's senses in your writing, it's rarely necessary to use the actual verbs of perception such as saw, heard, and smelled.  Ironically, these words distance the reader from your viewpoint character because they remind the reader that he is not actually living the story through the character."  In lieu of using the verbs of sensation, Marshall recommends that authors simply describe the sensation.

Example without verbs of sensation:

• Cisco paused at the back door of the livery stable.  The air reeked of prairie hay and manure.  On his right stood horse stalls. To his left, rows of saddle racks.  A horse whinnied and stomped its hooves. 

ACTION VERBS.  Distinct from the verbs of sensation are the action verbs needed to either:

• Maneuver the character into position to experience the sensation, or
• Describe an action the character must perform prior to being able to receive the sensation.

For example:

• Before a character can see, he may have to look
• Before a character can hear, he may have to listen
• Before a character can feel, he may have to touch
• Before a character can smell, he may have to sniff
• Before a character can taste, he may have to eat

Example where action verbs (in italics) set the character up to experience the sensation:

• Something in the air caught Cisco's attention.  He sniffed.  Smoke.  Mesquite wood.  He clutched his Colt 45, its grip soothing to his jittery nerves.  He edged closer to the door of the livery stable and peeked inside.

If the basic verbs of sensation are see, hear, feel, smell, and taste, then the plain-vanilla action verbs of sensation are look, listen, touch, sniff, and eat.  For each of the action verbs of sensation there are synonyms.  The number of synonyms available depends upon the sense being employed.  For example, Stephen Glazier's Word Menu software lists dozens of verbs of motion and dozens of verbs of sight, but none for hearing, touch, taste, or smell.  Synonyms for look include observe, study, gaze, glance, peek, and many more.  For touch there are caress, finger, handle, and so on.  For taste, there are various synonyms for eat, including nibble, chew, lick, bite, chomp.  The usable synonyms for listen and sniff are pretty limited: hearken? inhale? 

Whether or not action verbs are needed or desirable to help the character experience the sensation depends on the situation.  And sometimes action verbs are useful for other reasons, such as for dramatic effect, rhythm, or pacing.

MODIFIERS.  As a fiction-writing mode, sensation is particularly vulnerable to the overuse of modifiers.  Adjectives and adverbs tend to dilute the effectiveness of description; they tell rather than show.  This is especially the case with adverbs ending in -ly. 

Example using lots of adjectives and adverbs (in italics)

• Cisco paused at the weathered back door of the rickety, old livery stable.  The humid air reeked with the pungent smell of fresh prairie hay and the rank stench of horse manure.  On his right stood dilapidated horse stalls.  To his left, rows of dusty saddle racks.  A horse whinnied shrilly and stomped its hooves nervously. 

Example using fewer adjectives and adverbs

• Cisco paused at the back door of the livery stable.  The air reeked of prairie hay and manure.  On his right stood horse stalls.  To his left, rows of saddle racks.  A horse whinnied and stomped its hooves. 

Sometimes a modifier adds just the right touch, sometimes it deadens the sensation.  It's case by case, depending on a host of variables, including context, pacing, and tone. 

ONOMATOPOEIA.  Regarding the sensation of hearing, Ron Rozelle (Description & Setting) suggests onomatopoeia as a means of letting the reader hear things.  Does a fan merely spin, or does it whir?  Does a skeleton merely shake, or does it rattle or clatter ?  Onomatopoeia may function as either nouns or verbs.  For example:

• The duck quacked.
  
•  The duck's quack echoed across the valley. 

OTHER WORD CHOICES.  Fortunately (even beyond verbs of sensation, action verbs, adjectives, adverbs, and onomatopoeia) there is a rich universe of words available to portray sensation.  The choice of one word over another can make a difference in effectively conveying sensation.  For example, does a lover touch-or caress?  Should a particular smell be described as an aroma?  A scent?  An odor?  A stench?  Does the word generate a positive connotation or negative?  How does a change of words alter the emotional response?  Which emotions are stimulated by each word choice?  Sometimes the differences are subtle; sometimes they're substantial. 

COMPARISON.  According to Rozelle, "Saying what something smelled like or tasted like or felt like is always telling."  Similes and metaphors are important means of description in many forms of writing.  Sensation lends itself to comparison, but sometimes a sensation may be best described through contrast.  As in Rozelle's example of a tasteless stew, sometimes the most effective description is to describe what something doesn't taste like.

SYMBOLISM.  Sometimes sensation can take on a greater meaning.  According to Rozelle, ". . . using something seemingly small to enlarge or call attention to the bigger picture, will serve you well time after time."  Subtle use of symbols can be an effective means of reinforcing themes.  But, warns Rozelle, "The use of symbolism can be tricky business for a writer and can quickly go over the top.  Modern-day readers aren't as a rule very tolerant of blatant symbolism . . . ."

CLICHÉS.  The sensation mode of fiction-writing, to borrow a cliché, is a target-rich environment for clichés.  As stated by Rozelle, when depicting sensation, "Avoid giving your reader the overused clichés that she's read time after time after time.  Like a startled character being caught "like a deer in the headlights," or one gazing intently "staring daggers."  Those have been done to death.  But they are resurrected by far too many authors."

INTENSITY.  Sensation has a range of intensity, from overwhelming, on one extreme, down to the absence of sensation.  Think of movies where action scenes rumble with so much sound that it can shake your popcorn out of its box.  But then the aftermath may be marked by softness, silence, or darkness.  As explained by Rozelle, "There will be times when you will want to be loud."  On the other hand, "Sometimes the absence of something is the most effective description of all." 

CHARACTER EMOTION.  Sensation can create emotion within a character, and that emotion may be used to channel the story in different directions.  A character's attitude toward a sensation may reveal character.  Emotion may be used to transition into backstory.  Emotion may hint at a theme or help establish tone.  Emotions (such as fear, curiosity, frustration, anger, lust) may advance plot by propelling the character into action. 

READER EMOTION.  As explained by Rozelle, "When using the sense of touch, you won't always be describing what a character feels.  Sometime you'll be nudging your readers toward what you want them to feel when they read your fiction, so they can associate a feeling that they might never have experienced with one that they probably have." 

Many times the reader's emotional response will mirror the character's emotions, but sometimes not.  For example, a viewpoint character may enjoy torturing a victim, but the reader might be appalled.  A character may enjoy a tender love scene, but the reader may be horrified because one of the characters is a serial killer. 

PHYSICAL REACTION.  Often the best way to communicate a sensation is to portray the character's reaction to it.  According to Rozelle, especially "When its time to inflict a bit of pain and suffering in your fiction, put more emphasis on your character's reaction to it than on the actual description of it."  Which sensations would make your character's mouth water or his skin crawl?  Which sensations would make him gag?  Jump?  Duck?   Cough?  Hold his nose? 

Traditionally, in real life and in fiction, stimulus precedes response: first there is action then there is a reaction.  But according to Marshall, "To show a character's reaction to something shocking, break the action/result rule and show the reaction before describing what is being reacted to.  This may seem backward, but what happens is ". . . a tiny moment of suspense is created between the horrified reaction and the description of what's being seen."

Example of action followed by reaction (stimulus then response):

• A gun fired, and Cisco flinched. 

Example of response preceding stimulus:

• Cisco flinched.  A gunshot.
