Hi I would like to know if わけない is the shortened version of わけがない / わけはない (it is not possible that)

I am pretty sure it is but it would be nice if I had some confirmation. I would like also to know what nuances it bring (if any)



Hey, Aqua, you got any cash ?

What do you think ? As I had time to grab my wallet when you dragged me off here !

According to Tae Kim (of course, not always the best of sources) and Jisho it is.

Tae Kim (from Hypothesizing and Concluding):


There’s no way I can read Chinese. (lit: There is no reasoning for [me] to be able to read Chinese.)

Under the normal rules of grammar, we must have a particle for the noun 「わけ」 in order to use it with the verb but since this type of expression is used so often, the particle is often dropped to create just 「~わけない」.



[...] 2. there's no way that ... (​Usually written using kana alone, See also わけがない, contraction of わけがない)

Also, Imabi uses it interchangeably in his (their?) Wake + Negation article:

  1. 英語えいごはおろか、中国語ちゅうごくごも学まなべるわけないでしょう。
