I am pasting in all the graphemes which have more than one pronunciation, but am putting at the very top the ones that make children stumble the longest, because they have different sounds not just in a few words, like in ?said, plait, plaid?, but in dozens. Although high frequency words with variant sounds (said, any, many) can cause a lot of problems, even though their number is small.
Overall reading progress in English is most impeded by the following 7 phonic inconsistencies. The worst is and all graphemes with . These are the main trouble makers, with some rarer ones further down:
: (on - only, once, won, woman, women
go - to)
: (shout - should, touch, soul, soup)
: (home - come, move)
: (food - good, flood)
: (treat - great, threat, theatre, create
(ear: ear ? early, heart, bear)
surplus endings
which do not lengthen vowels
(have, delicate, engine -
cf. gave, dedicate, divine)
omitted doubled consonants (camel)
which make short vowels look long
(same, camel - cf. hammer)
