Here's some examples of english's rediculous orthography.
trick vs disc which words use ck, k, or c. You just kinda have to memorize it.
Then we have our borrowed words like euphemism pronounced yufamism. yup, gotta memorize those too.
Then our random choices about our vowels sea, see, ceiling.
and then our homonyms like bank (of a river), bank (where you store money), bank (the action of storing), and bank (to ricochet -there's another borrowed word to memorize-)
And our homographs like read (present tense) and read (past tense) which depend on context
And finally the irregular inflections between present and past, single and plural.
English is like a spoiled toddler that steals things from other kids and then pretends that it has always been theirs.
In all seriousness, no, English is not from an outsider's perspective.
We make up for our lack of bilinguality in America by learning a language that has several others crammed somewhat-intelligibly inside. I love it but would never choose to learn it if it weren't my native language.
Just about everything said about English in this conversation has to do with the orthagraphy of English rather than the spoken language. A child learning English becomes fluent without thinking of any of this except possibly the problem of homophones. As difficult as the English writing system is, it is no more challenging than that of Japanese or Irish. English is a difficult language but not simply because of its spelling. Danes and Germans don't have half the trouble with it that speakers of non-Indo-European languages do. It is the features of grammar and usage peculiar to English which make the language relatively difficult according to the degree of difference from the learner's native language.
Dude, a child could learn ANY ridiculous language, due to how the child's brain works.
Like, there have not been any studies for reasons of ethics--but based upon modern day understanding of how children have a boost on learning their first language (toddlers are literally a different animal than children and adults)... you could easily put together a language that is garbage on so many ridiculous levels. Like Volapuk turned well past eleven... and the child would have no issues picking it up, as the child's first language. Just due to how language centres of the brain work when unprototyped.
