Note the verb form 〜ざる is a left over from a classic form that is now pretty much out of general use. (Don't ask me more, please ;-)
Hmm, on second thoughts I'm only about 60% sure it's the negative of うる and not the negative of える. That word's a pain.
isnt える and うる the same verb in this case?
Please see the comment by bamboo4 in [uru]. ざるを得ない is one word and always read as ざるをえない. There is no ざるを得る.
Formed from v-nai base + ざるをえない. e.g. 行く→行かない→行かざるをえない Vn = V-nai base
ざる is an archaic particle indicating negation. It's root form is ず and it inflects as ず/ざら、ず/ざり、ざる/ぬ、ざれ/ね but its imperative form is ざれ. In tbis manner, it has very unique inflections. 行かざる means not going, which is denied by えない so that it becomes "not going is not capable," the double negative thus resulting in "I must go."
#4293 is not acceptable. 同情の涙を禁じ得ない would be the correct diction. ざるを得ない is not appropriate so that this example does not belong to this head.
#4293 grammatically is not wrong, but the meaning is very strange. Because 〜ざるを得ない means you have to do 〜even you don't want to, and 禁じる means 抑える or suppress, So, 同情の涙を禁じざるを得ない means: You have to suppress tears of sympathy, even if you didn't want to (suppress). Whereas, 同情の涙を禁じ得ない means(which is more natural in this case): You couldn't suppress/stop tears of sympathy (of dropping down).同情の涙を抑えることができない
Thank you guys. I felt something wrong but I didn't notice that point. I found a better entry "kinjienai" for the example but I cannot do now.
