STEP 1

Group the words by the silent letter

Start with b in thumb, comb, and climb. Then try the initial letters in psychology, pneumonia, and mnemonic. Their spellings preserve letters that do not appear as separate sounds in the listed pronunciations. The practice notes tell you which sound to start or finish with instead.

STEP 2

Keep the neighboring consonants

A silent letter does not make all nearby letters silent. Doubt still ends in t, hymn still ends in m, and sword still ends in d. Use the IPA to check the remaining sounds and listen for them in the video. Practice the whole word before inserting it into a short phrase.

STEP 3

Make a listening check

Choose five words and write down your prediction about the silent letter in each. Watch the examples and revise your list. For an extra round, compare debt and receipt in the business guide, or salmon in the food guide. Learn each word rather than assuming a spelling rule has no exceptions.
