A suffix is a specific group of letters at the end of a word. It often indicates part of the meaning of the whole word.
Example: “less” = without
If you know the most common suffixes, it will help to deduce the meaning of new words.
I had a sleepless night at the hotel.
You already know the word “sleep” and now you know that the suffix “less” means “without”. Therefore you can deduce that the sentence means: “I had a night without sleep.”
Use a good dictionary to check the meaning of all new words.
There are 2 main types of suffix in English:
