Writing : Descriptive essay .

A descriptive paragraph or essay is characterized by the use of Adjectives. it tells how something looks, feels, smells, tastes, and/or sounds. A good description is a word picture; the reader can imagine the object, place, or person in his or her mind. Here is an example of a Descriptive paragraph:

When I was  two or three years  old, I lived in a  house  that had a  strange,
atmosphere. I do  not remember anything a bout the house  except the stairway.
It was  dark, squeaking, and quite  narrow, and its  steps were a  little  high for me
to c limb  up. From the  bottom of the stairway, it seemed like  an endless  climb
to the  top. Beyond the  darkness  at the  top  of the  stairway, there  was  an
elegant, middle-aged lady leaning against the wall. I had  to pass  her every time
I went to my room, for my room was  the first room beyond the stairs on the
second floor. The lady wore a  beautiful dress  with a  quiet pattern and a tinge
of blue, and her peaceful eyes stared at me every time I went up  the stairs. As
I carefully climbed up the last step, her eyes became  fixed on me. She didn’t
talk, nor did  she move. She  just stood there and watched me climb up  the
stairs. one  day I touched her, but she  did  not react.HeR face did  not change
expression, nor did  she even blink. She  just kept staring at me with her
glittering eyes. Later, we  moved out of the house, and I never saw her again.
Now I know that the  lady was a  mannequin. My aunt, who lived in the
house , used  it for her dress making class.
