A Brief Guide to Grammar and Punctuation

Glossary

  • Adjective - describes a noun (The pretty girl)
  • Adverb - describes a verb (He ran quickly)
  • Apostrophe - denotes possession (David’s cap) or an omission of a letter (I’m fine)
  • Colon - indicates a significant pause between two closely related phrases, or indicates the start of a list (The winners are: )
  • Comma - denotes a pause in a sentence (Excuse me, are you Margaret Thatcher, or do you just look like her?) and can be used to break up items in a list (I need eggs, flour, milk and bread)
  • Hyphen - a link which joins two words together
  • Infinitive - the ‘whole’ form of a verb, constructed in English with ‘to’ (to buy). Splitting an infinitive means breaking up ‘to’ from its verb: (To boldly go) is a split infinitive
  • Noun - denotes a person, place or thing
  • Semicolon - indicates a pause shorter than a colon, but longer than a comma, and links two closely related complete phrases
  • Verb - denotes an action

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>

  • trolley - trolleys
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:

  • In James’ opinion

  • Their patio wasn’t as impressive as the Jones’

  • The ladies’ room

A word with an irregular plural still takes the <’s>

  • The children’s playground

  • The people’s votes

  • The men’s eyes                        

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:

  • I am studying full time

  • They are all in their first year

Adjectives (which refer to nouns) do have a hyphen:

  • I am a full-time student 

<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):

  • I went to see him – it took me hours – and he was delighted that I’d made the effort

Commas

Are used to separate lists of nouns or phrases side by side:

  • I had chickenpox, mumps, German measles and scarlet fever when I was little

A comma should not normally be used before ‘and’ in a list:

  • Chocolate, milk and raspberries

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:

  • My boss, who normally wears a suit, was looking really scruffy today

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

  • The following people were suspected: the butcher, the baker, the candlestick maker

b) to make a strong contrast between ideas in a sentence

  • Cannabis is illegal in the UK: The Netherlands have legalised cannabis use for some time now

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:

  • This is a very isolated place; I get quite lonely
