In our new course ‘Say it right!’, I am teaching you all the basic reading rules which you need for pronouncing the most words in English without problems. Here are some major ones:

1) Don’t accentuate (=pronounce clearly) the final suffixes and unstressed syllables in long words.
‘-ous’ (sounds like /es/) various, serious, nervous, obvious, previous, dangerous
‘-tion’ (sounds like /shin/ not /shon) information, section, decision, population, association, organization, position, commission
‘-ture’ (sounds like /che/) future, feature, creature, moisture, picture
‘-ate’ (sounds like /et/ not /eit/) corporate, desperate, private, separate, adequate
‘-able’ (sounds like /ebl/ not /eible/) questionable, reliable, doable

2) Combinations of vowels e/i/y/u with ‘r’ in the middle of words – they all sound the same /ɜː/ like in ‘girl.
All these words will sound the same: girl, term, turn, burn, spur, Myrtie, shirt, bird, heard, early, thirsty, skirt, fur, dirty, curse, work

3) You need to remember words with silent letters (=letters which are written but not pronounced).
Some of them: (letters in red are not pronounced)
honest, hour, ghost
knife, knot, knee, knitting, knock
autumn, damn, column
bomb, numb, climb, lamb, doubt, plumber, debt
resign, design, foreigner
guest, guess, colleague, guilty, tongue, biscuit
almond, palm, calf, half, talk, walk
write, wrap, wrist, wren, wrong

Make sure you pronounce all these words right. You can check yourself in this audio guide here
We have recorded a video course covering the most important spelling/reading/pronunciation rules in English so that you could work with the videos at your own pace.
