By the way.
>>21 "dattebayo"
almost It means as same as "dayo".
"kore ha hon dayo" = "kore ha hon dattebayo"
"dattebayo" is more importunate/stress than "dayo", I think.
though "dattebayo" is not common.
>> "korae"
there is not "korae" in Japanese.
hm……"こらえる(koraeru)" means "stand" in English.
"こらえがたい(difficult to stand)" "こらえられない(can't stand)" etc.
