So there you have it, we’ve got 20 advanced English adjectives. Adjectives, as I said, are for describing nouns. I haven’t used any of the ordinary adjectives big, small, bad, little long, whatever.

And it would be great if you could try and practise some of them. Take them, take the examples that I’ve given, and try to make your own examples to practise them.

And don’t worry if you forget some of them, just try to remember three or four and then move on from that and drop them into your speech from time to time.

And if you need any more help, any other help you know where I am, just come back to me at englishlessonviaskype.com
