What constitutes a look? Depending on its purpose, a look may be quick, long, pleasant, or nasty, among others.
Definition: as a verb, “to direct one’s gaze toward someone or something, or in a specified direction;” as a noun, “an act of directing one’s gaze in order to see someone or something.” (Google .com.) A look, therefore, is an act intended to focus attention on the object of the look. A simple gaze, however, may reveal more than desired; such as disclosing the gazer’s state without expressing a word. Lets look at some “look” alternatives:
Sneaky: A peek, peer, or peep suggest an unobserved look; such as peeking, peering, peeping through a keyhole, like a Peeping Tom hoping for an eye popping look.
Lengthly: To examine, witness, study, inspect, observe, or scrutinize suggest a more intense look with a fully focused mind to evaluate the subject matter.
Quickly: A blink, glance, glimpse, scan, or browse suggest a cursory look, without much focus on mental attention.
Emotional: To glare, glower, or gloat express emotion, as anger, annoyance or triumph in the eyes of the beholder.
Intense: To fixate, stare, gape or gawk suggest an intense, lengthly look, with gape adding an open mouth in disbelief or wonderment.
Lustful: To ogle (desire) or to leer (lecherous) suggests a prurient interest in the subject matter. I suppose one could ogle or leer with a gape, depending on the lollapalooza of interest.
At least one look word, “peruse”, expresses diametrically opposed meanings; i.e., to scan quickly or study intently, as “a. to examine or consider with attention and in detail; study; b, to look over or through in a casual or cursory manner.” (Merriam-Webster Dictionary) I suppose, the nature of a peruse depends on how you look at it.
In addition to the above, a look may also be: amorous, askance, beaming, bewildered, compassionate, impertinent, mischievous, provocative, defiant, roguish, ferocious, piercing, fearful, contemptuous, scornful, sheepish, knowing, lingering, incredulous, indignant, vindictive, grateful, icy, to name a few.
Accordingly, when taking a look at someone or something, you have a full palate of colors at your disposal either to reveal your mood, or conceal it with controlled deception. The look is yours.
