She need not say how obliging she feels.

She does not need to say how obliging she feels.

Is there a difference in meaning between the sentences? Thanks.

Same meaning

She need not say how obliging she feels.

She does not need to say how obliging she feels.

Is there a difference in meaning between the sentences? Thanks.

Neither means much to me. I cannot think of any situation in which anybody might need to say how obliging they feel.

Thanks, 5jj.

If I changed the word to 'obligated', does it make sense? And, if so, do the sentences have the same meaning?

 

[5jj]

That makes more sense. There is no real difference in meaning between the two sentences.
