The idea

Most spelling marks are lost on a small set of words and word endings. Learn the rules for adding endings, and learn each hard word by its tricky part: ‘necessary’ has one c and two s's, ‘accommodation’ has two c's and two m's, ‘embarrassed’ has two r's and two s's, ‘definitely’ contains ‘finite’.

Commonly confused words sound alike but do different jobs. Do not go by sound. Work out the job the word does in the sentence: is it a noun or a verb? Does it show possession, or is it short for two words? Then choose the spelling.

In British English, practice is the noun and practise is the verb.

Rules to remember

Common mistake

Students write ‘practice’ for the verb. Put ‘advice’ or ‘advise’ in the same place and listen: if ‘advise’ fits, the word is a verb, so write ‘practise’.

Worked example

Choose the words: ‘______ going to ______ the final if they do not train.’ (Their ... loose / They're ... lose / There ... lose / They're ... loose)

  1. The first gap means ‘They are going’, so it needs the short form ‘They're’.
  2. The second gap is a verb meaning ‘not win’: ‘lose’, with one o.
  3. ‘Loose’, with two o's, is an adjective meaning ‘not tight’, so it cannot fit.

Answer: They're ... lose
