I have learned Lithuanian, Russian, German, French, Spanish and Italian as well as English, and taught some of them too. Phonics was completely sufficient for learning to read all except English. With phonic spellings, u never need anything but phonics.
Only English spellings have more than one sound (go/do, sound/soup, man/many) and pose reading as well as spelling difficulties. Learning to spell French takes a while too, but not as long as English.
Because I did not learn English until the age of 14 and learned the spellings and meanings of words together, one by one, I did not quite realise just how awful English spelling is, until I stopped teaching and took a really close look at the English spelling system.
Anyone who claims that English spelling is not very different from other writing systems does not know what they are talking about. It is exceptionally irregular and learner-unfriendly.
