English Words that can be commonly confused for ESL learners

Words that sound alike or look alike (moral/morale) often confuse students, especially those using spell checkers. This lengthy list of commonly confusedwords with simple definitions will help you decide which spelling fits your sentence.
Take a look at these two sentences – one of them contains a mistake:

I poured over book after book.

We pored over the catalogues.

Are you uncertain which one is right? There are a lot of words in English that look or sound alike but have very different meanings, such as pore and pour or flaunt and flout. It’s easy to get them confused and most electronic spellcheckers won’t be much help in this type of situation: they can tell you if a word has been spelled wrongly but they can’t generally flag up the misuse of a correctly spelled word.
Here’s a quick-reference list of pairs of words that regularly cause people problems. The words follow the accepted British English spelling. Some of them do have alternative American spellings and you will find these at any Oxford Dictionaries.
