Can I use Punctuation and Grammar?
Basics



for punctuation and grammar:
Every sentence must start with a capital letter.
Every sentence must finish with some form of punctuation: .?!
Proper nouns need capital letters. These are unique people, places or things e.g. there are many cities so
‘city’ doesn’t take a capital letter. However there is only one London, therefore it takes a capital letter.
 Remember don’t mix up ‘was’ and ‘were.’ For example ‘I was (singular)’ and ‘We were (plural)’
