EllaDee - When I asked you to link to the "research by experts" you were claiming exists and says English is oh so difficult, I was not asking you to write down the names of first five books you had heard of. I asked you to link to one such research. Please do, if you can.
Meanwhile, have a look at this fascinating article from The Economist about some truly difficult languages. In the first page, you will see:
It may be natural to think that your own tongue is complex and mysterious. But English is pretty simple: verbs hardly conjugate; nouns pluralise easily (just add ?s?, mostly) and there are no genders to remember.
English-speakers appreciate this when they try to learn other languages. A Spanish verb has six present-tense forms, and six each in the preterite, imperfect, future, conditional, subjunctive and two different past subjunctives, for a total of 48 forms. German has three genders, seemingly so random that Mark Twain wondered why ?a young lady has no sex, but a turnip has?. (Mädchen is neuter, whereas Steckrübe is feminine.)
English spelling may be the most idiosyncratic, although French gives it a run for the money with 13 ways to spell the sound ?o?: o, ot, ots, os, ocs, au, aux, aud, auds, eau, eaux, ho and ö. ?Ghoti,? as wordsmiths have noted, could be pronounced ?fish?: gh as in ?cough?, o as in ?women? and ti as in ?motion?. But spelling is ancillary to a language?s real complexity; English is a relatively simple language, absurdly spelled.
Perhaps the ?hardest? language studied by many Anglophones is Latin (...) Yet are Latin and Greek truly hard? These two genetic cousins of English, in the Indo-European language family, are child?s play compared with some. Languages tend to get ?harder? the farther one moves from English and its relatives.
