Spelling and Grammar
Plurals
Certain words change their spelling when pluralised:
- potato - potatoes
- tomato - tomatoes
Some have odd, or irregular spellings in the plural:
- ox - oxen
- child - children
- woman - women
Words ending in <y> normally drop the <y> and add <ies>:
- secretaries
- hobbies
- ladies
Words ending in <vowel + y> take the usual <s>
Prefixes (stuck on to the beginning of a word)
Adding a prefix to a word does not alter its basic spelling:
- dis / appear
- dis / organised (not unorganised)
- pro / claim
- un / necessary
Suffixes (stuck onto the end of a word)
< - ly> - This suffix creates an adverb. It is
straightforward and added to most words:
- freely - lively - quickly
< - ing> - This is added straight onto the ends of words, except
those which end in <e>. Words that end in <e> + <-ing> = drop the <e>
- moving - diving - placing
If a word ends in a consonant and the suffix begins with
a vowel, the consonant is doubled:
- fit - fitting
- occur - occurred
- big - bigger
These suffixes can all double a consonant: <-ing, -er, -est, -ed>
Consonant changes before a suffix
Word ending in <t> + <sion> = <t> changes to <s>
- convert - conversion
- divert - diversion
Word ending in <y> + <ness> = <y> changes to <i>
-
happy - happiness
-
lovely - loveliness
Words ending in single vowel + single <l> = <l>
changes to <ll> before any suffix
-
typical - typically
-
unravel - unravelled
-able and -ible
These simply have to be learnt! Here are some of
the more common ones:
-
commendable
-
audible
-
possible
-
unavoidable
-
flexible
-
terrible
-
dividable
-
legible
-
visible
-
tenable
-
permissible
-
infallible
Homophones (Words which sound the same but are spelt
differently)
Be aware of:
-
licence (noun) - license (verb)
-
a driving licence - a licensed driver
-
affect (to produce an effect on) -
effect (to bring about, to accomplish)
-
She affected illness / affectation - to
have an effect on / effective
-
stationery (paper, pens etc) -
stationary (not moving)
-
your (possessive) - you’re (you
are)
-
our (possessive) - are (being -
we are)
-
their (possessive) - they’re
(they are)
Punctuation
Apostrophes
Signify:
-
a) possession
-
b) something missing
a) Possession
With a singular noun, the apostrophe goes before
the <s>:
-
Claire’s hat
-
The cat’s blanket
With a plural noun, the apostrophe goes after the
<s>:
-
The boys’ game
-
Students’ Union
If a word already ends in <s>, then the
apostrophe alone signifies possession; no <s> is needed:
A word with an irregular plural still takes the
<’s>
b) Omission of a letter
-
It’s okay, I’m alright
-
you’re right
-
don’t worry
*NB. It’s always means ‘it is’. If it does not
mean this, don’t use an apostrophe.
Apostrophes are never used to denote the plural:
-
Apples (not Apple’s)
-
Pears (not Pear’s)
Hyphens
The hyphen is a link which joins two words
together. The University House Style has the following rule:
Nouns which are comprised of two words have no
hyphen:
Adjectives (which refer to nouns) do have a
hyphen:
<well> + an
adjective uses a hyphen:
-
A well-written essay
-
A well-dressed woman
To indicate an aside in a sentence, use a hyphen
with a space on either side (the computer will automatically convert
it to an em-dash which is slightly longer than a hyphen):
Commas
Are used to separate lists of nouns or phrases
side by side:
A comma should not normally be used before ‘and’
in a list:
Except when a comma puts a necessary pause in a
sentence, or when a list would not make clear sense without one.
Look at the difference between these sentences in
terms of comma use:
-
a) The work will be undertaken by Peterson
Brothers, Abercrombie Jones, and Parker and Knight Industries
-
b) The work will be undertaken by Peterson
Brothers, Abercrombie, Jones and Parker, and Knight Industries
Commas can also indicate a pause in a sentence:
Colons
A colon indicates a substantial pause between two
parts of a sentence, but suggests a close connection between them.
It is used:
a) to introduce lists
b) to make a strong contrast between ideas in
a sentence
Semicolons
Indicates a pause shorter than a colon, but
longer than a comma.
It splits phrases that a grammatically complete (ie
they can stand alone as a sentence) but which are very close in
meaning:
