Practical English Usage

Practical English Usage is a world bestseller and a vital reference tool that helps teachers and higher-level learners with common language problems in English.
It is now available as an app, making it quicker and easier to look up the 600+ entries.
The app has been developed by Oxford University Press, the world’s most authoritative English-language reference publisher, working together with Paragon Software Group, a leading software developer for mobile devices.
Practical English Usage provides instant answers to questions about the English language which both native and non-native speakers of English find difficult to explain: When do we use a past tense with a future meaning?
When and why do English speakers use 'the'?
Do I say 'big', 'large', or 'great'?
What exactly is the difference between 'close' and 'shut'?
How do I read out an email address?
