You want a tough language? Try ENGLISH! Aargh!!
Things that suck about English:
(1) Almost every rule has a list of
exceptions. e.g.: i before e except after c. And w. Sometimes.
(2) Words are often
not spelt phonetically (i.e.: the way they sound). e.g.: "Freedom is the right of all sentient beings" written more phonetically would be
"friidm iz θə rait ov ôl senʃənt bīiŋz." - and letters don't always hold the same value. e.g.: the letter "g" is pronounced differently in the words 'go,' 'giraffe,' 'thought,' 'cough' and 'sing.'
(3) English is a hard language to pronounce. A native Japanese speaker produces approximately 110 separate phonemes. A native English speaker produces in excess of 8600 phonetic units!
