Hi friends,

Could you please explain the use of "no good"... ?

"I began to worry, for I dreamed I had forgotten the words which would open the combination locks. I tried hard to remember but it was no good"

Thanks

Mister Micawber thank you so much.

Could you please assist me how can I learn such techniques to understand the sense of the sentence instead of concentrating on common use such as we use good for something useful.

I just understand is that

No good = something is not good

but how come it can be taken for unsuccessful ?

Emotion: zip it

Best regards,
It is idiomatic.

I tried hard to remember but remembering was not good.
I tried hard to remember but remembering was no good.

I tried hard to remember but it was no good.

From perhaps these definitions of 'good':

sufficient or ample: a good supply.

advantageous; satisfactory for the purpose: a good day for fishing.

And related to these idioms:

come to no good, to end in failure or as a failure: Her jealous relatives said that she would come to no good.

make good,
to be successful

to carry out; accomplish; execute: The convicts made good their getaway.
