Normally, texts which contain technical terminology will incorporate definitions and
explanations. This is particularly the case if the text is aimed at non-experts or students of
technical subjects. A term should be defined if the word or phrase used
1: is unfamiliar to the reader2: has multiple meanings3: has a specific meaning in that discipline. The same word in one discipline
can mean a different thing altogether in another discipline
A definition is:
a statement which gives clear, exact, concise description or explanation of a statement ofthe meaning of a word or phrase or the nature of an object
When writing definition, some common words and expressions could be used, such as:
Examples:
1. A computeris an electronic device.
2. Exercises are physical and mental activities.
3. The term laboratory refers to a room or building used for scientific research.4. Arachnophobia means that a very strong fear or hatred of spiders.
Elements of Definitions

Unit 2: Types of Technical Documents UWB10402 Technical Communication 1
Plain English the purpose of definition is to clarify meaning, so use languagereaders could understand
Examples:
compare:
i) A tumor is a neoplasm
ii) A tumor is a growth of cells that occurs independently of surrounding
tissue, and serves no useful function.
Basic properties definition should convey the properties that differentiate it
from all others.
Examples:
i) A thermometer measures temperature
ii) A book can be used to write in, to display pictures, and to record financial
transactions.
iii) A book is a bound volume of pages.
17
Neoplasm this word is still
unclear and needs more ex lanation
This is better because it gives
accurate description of the
term
This is essential information
and gives real meaning of theterm.
For this term, it cannot be defined according tofunctional properties because books have multiple
functions.
Therefore, the basic property of theword that we could use is physical.

Objectivity we need to omit our opinions from a definition, unless readers ask
for them.
Examples:
i) Bomb is defined as an explosive weapon detonated by impact and a timingmechanism.
ii) Bomb is an explosive weapon devised by some idiots to blow up the world.
2 types of definitions
1: the short formal definition of one sentence
2: the extended definition of several paragraphs or of the whole process
The short formal definition
Usually of one sentence that contains 3 parts
1. the term or word or phrase to be defined
2. the class of object or concept to which the term belongs
3. the different characteristics which distinguish this term from all others of
that class
18
This definition gives fact.
some idiots to blow up the world is opinion
and the definition ignores a bombs basic
property.

Water is a liquid made up of molecules of 2 parts of hydrogen to 1 part of oxygen.
Topaz is a mineral which is transparent or translucent
aluminium silicate, usually yellow incolour and used as a gem.
A pencil is an instrument for writing or drawing, made of thinrod of graphite, enclosed in a wooden
cylinder.
In writing short formal definition, there are 2 rules:
1. Specific class differentiation
Assign the term to a class and then detail precisely how this term differs
from other term within that class
Example:
An elephant is a huge mammalorder of Proboscides, of the suborder Elepantoidea.

Rule 2:
No repetition of word.
Never repeat same word used in definition as it is a weak definition. Itdoes not tell the reader any new information.
Use another word to give more information.
Example:
A postman is a man who carries and delivers letters.
A postman is a mail carrier who delivers letters.
Now, lets try giving a short, formal definition to the following terms:
Word / term Verb Class Differentiating characteristics
Hay is grass mown and dried for cattle food.
A headache is a continuous pain in the head.
1. A heart
2. A supermarket
3. A clock
4. A volcano
5. An engineer
6. An orchid
7. A dolphin8. A computer
9. A mobile phone
10. A bicycle

Unit 2: Types of Technical Documents UWB10402 Technical Communication 1
Some definitions and explanations give further distinguishing characteristics bymeans of a defining relative clause.
Expanded definition that involves more than one sentence.
It could be written in a paragraph or more, or even a whole essay to clarify the
definition. This depends on the topic for each discipline and the need for details to achieve
the purpose of writing it.
Relative clause includes relative pronouns which are:
Ways to extend a definition:
1. Etymology or Derivation
Refers to the origin of the word, its multiple meanings, and the way the
word is used up to the present time.
Examples:
i. Alcoholhas its original roots from the Arabic word al-kuhul, which meant a
colourless, inflammable, and pungent liquid with the chemical properties of
C2H6O. Alcohol today can be burned as fuel, used in industry and medicine,
and can be intoxicating element found in whiskey, wine, beer or in fermented
and distilled liquors known as ethyl alcohol.
ii. Nicotine has its roots in the French word nicotiane, which means the tobacco
plant. This Nicots plant was named after Jean Nicot, French ambassador at
Lisbon. He introduced the tobacco seeds to France in 1560. This tobacco plant
is poisonous water-soluble alkaloid, C10H14N2, found in the tobacco leaves
which are used ordinarily in an aqueous solution of its sulphate as an
insecticide. When the smokers of tobacco leaves became addicted to smoking,

D. Detailed characteristics of each division i) physical characteristics, (ii) location
(iii) uses
5. Compare and Contrast
Use of analogies can compare the unfamiliar with the familiar based on a
pattern of similarities. In doing this, we need to ask the following
questions when giving definition:
Does it resemble anything familiar?
How does it differ from comparable things?
How is it both similar and different?
Examples:
i. The way the animal heart pumps blood throughout the body is like the way
water pump works to pump water into the water pipes.
ii. A seam gauge resembles a short ruler, except it has a length wise slot in the
middle of its entire length.
iii. Fiber optics technology results from the superior capacity of light waves to
carry a communications signal. Sound waves, radio waves, and light waves
can all carry signals; their capacity increases with their frequency. Voice
frequencies carried by telephone operate at 1000 cycles per second, or hertz.
Televisionsignals transmit at about 50 million hertz. Light waves, however,
operate at frequencies in the hundreds of trillion of hertz.
In addition to the 5 ways of expanding a definition above, we can also use descriptive
details where we elaborate details like class, size, shape, colour, properties, uses and
other information which we think are helpful in clarifying the term. Other than that, we
can use examples and incidents, and we can also combine several ways in order to help
with the understanding of the term.

Exercises
1. The following are 2 samples of extended definitions written by a group ofstudents. Read the samples and identify:
a) the term, the class, and the differentiating characteristics
b) which way they used to define the term
c) whether the definition is successful in explaining to readers what the term
means

Scientific calculator is an electronic device that
people use to calculate mathematics equation.
This device is made up from electronic
components. The case is made up from hard
plastic. The structure consists of buttons and
screen. The buttons are used to type in numbers
and mathematics symbols. The function of the
screen is to display what is being punched from
the buttons.
Mechanical pencil consists of two terms that are
mechanical and pencil. It is called mechanical
because the pencil is produced by machines and
it consists of a set of moving parts that does a
certain task. While pencil is a type of stationery
used to write. So mechanical pencil is not like
conventional pencil because mechanical pencil
uses spring to eject the thin carbon lead from
the body in order to write. Whereas, the normal
pencil needs to be sharpened in order to write.

A stapler comprises many components, most of which are metal
stampings and spring type parts. Main components of a typical
home or office stapler include the base; the anvil (the metal plate
over which you put the document that you want to staple); the
magazine (which holds the staples); the metal head (which covers
the magazine); and the hanger (which is welded to the base and
holds the pin that connects the magazine and base). Rivets are
used to keep the parts together, and a pin is the hinge point for the
top and bottom half. There are also rubber and plastic materials
used both in enhancing the product and in making the stapler
cosmetically appealing. The springs in a stapler typically perform
two separate jobs: they keep the row of staples lined up in the
track and ready to be used, and they return the plunger blade to its
original up position. (The plunger blade acts as a guillotine, in that
it separates one single staple from the row of staples each time it is
