Using your English–English dictionary
This kind of dictionary helps you actually learn English.
Using headwords and parts of speech
1 Find the correct headword.
These bold words in a dictionary are in alphabetical order. Look
at the words on the top left and top right of the double page. Find
words which come just before and after your word.
2 Find the correct meaning.
If there are different meanings of the word, they appear in a
numbered list. Look at all the meanings before you choose the
correct one in context.

Using your English–English dictionary
Using headwords and parts of speech
3 Find the correct part of speech.
Sometimes the same headword appears more than once,
followed by a small number. This means the word has more
than one part of speech, e.g., n and v. Work out the part of
speech before you look up a word.
Clues:
• Nouns come after articles (a/an/the) or adjectives.
• Verbs come after nouns or pronouns.
2.1 Vocabulary
A How can an English–English dictionary help you
understand and produce spoken and written English?
The following information is useful for spoken English:
 stress
 pronunciation of individual phonemes – particularly when
a phoneme has multiple pronunciations
The following information is useful for written English:
 information about the type of word – C/U; T/I
2.1 Vocabulary
A How can an English–English dictionary help you
understand and produce spoken and written English?
The following information is useful for written English:
 the spelling – students might make the point that if you
don’t know the spelling, you can’t find the word in the first
place, but point out that you can often guess the possible
spelling – for example, medical could be medik but if you
don’t find it there, you can try medic …
 examples of the word in use to memorize
 some synonyms for lexical cohesion – this is a very
important point, although you may not want to elaborate
on this now
2.1 Vocabulary
B Study the dictionary extract on the opposite
page.
1 Why are the two words (top left and top right) important?
They tell you the first and last words on the pages to help you
locate the word you want.
2 How many meanings does medication have? What about
medicine?
Medication – one meaning; medicine – two, plus of course the
plural of the second definition of medications because it is a
countable noun.
3 Why does the word medical appear twice in bold?
Because the same word can be an adjective or a noun.
2.1 Vocabulary
B Study the dictionary extract on the opposite
page.
4 What do we call a doctor working in the armed forces?
A medic.
5 Where is the stress on medicine? What about medicinal?
Medicine – on the first syllable; medicinal – on the second
syllable.
6 What is the pronunciation of c in each bold word in this extract?
Sometimes /k/, sometimes /s/ – can students spot the pattern
that c+a = /k/, c+i = /s/, i+c = /k/ (as in medic)?
7 What is the pronunciation of a in each bold word in this extract?
Two pronunciations – /eɪ/ or /Ə/.
2.1 Vocabulary
B Study the dictionary extract on the opposite
page.
8 What part of speech is medicated?
Adjective.
9 Can you say Your medications are out of date? Explain your answer.
No – because medication is uncountable.
10 Can we write: Did the doctor medicate appropriately? Why (not)?
No – because medicate is transitive, so it must have an object.

Magnetic resonance
imaging (MRI)
a radiology technique that uses
magnetism, radio waves and a
computer to produce images of
body structures
revolutionized diagnostic capacities,
increased accuracy of disease
detection (in particular to the head,
trauma to the brain)
Laser surgery
surgery carried out using a
narrow beam of light radiation
or a laser beam to cut through
tissue
enabled doctors to carry out
microsurgery, increased precision,
recovery period is reduced compared
with traditional surgery
Discovery of DNA
structure
one of two types of molecules
that encode genetic information
led to developments in screening for
genetic diseases, for example
Research into
endorphins
hormones produced in the brain
that reduce feelings of pain
led to finding a treatment for

Think of research questions. In other words, ask yourself:
What must I find out from my research?

Look at headings, sub-headings, illustrations, etc. Look for
patterns or variations in presentation, e.g., a series of dates;
words in bold or italic script. Think: What information do
they give me?

Decide how to record information from your reading. Choose
one or more methods of note-taking. See Unit 1 Skills bank.

Using topic sentences to summarise
The topic sentences of a text normally make a good basis for a
summary. Follow this procedure:

Locate the topic sentences.

Paraphrase them – in other words, rewrite them in your own
words so that the meaning is the same. Do not simply copy
them. (This is a form of plagiarism.)

Add supporting information – once again, in your own words.

Check your summary. Check that the ideas flow logically.
Check spelling and grammar. If your summary is short, it
may be just one paragraph. Divide a longer summary into
paragraphs.

B The lecturer has asked you to research
vaccinations.
What do you understand by the term?
Vaccination involves the administration of a preparation that
allows the body to develop resistance to a disease without having to
be exposed to it.
2 Think of good research questions before you read the text on the
opposite page.
The three questions from Lesson 2.2 would be fine, although
students may come up with better ones.
3 Look quickly at the text. What is the best way to record
information while you are reading?
A timeline would be an appropriate form of notes (See Unit 1
Skills bank).

One of the greatest achievements of 20thcentury medicine was the global eradication of

number of people killed, etc.)
Smallpox is caused by the variola virus and is

transmission of the disease, incubation
period and symptoms of the disease)
The first attempts to control the disease used
a technique known as variolation.
initial techniques used (what is variolation
and to what degree was it successful?)
