Could you please tell me the meaning of 'would' in the following sentences:
1 He would seem to be getting better.
(Does it mean you the speaker lack of knowledge about his health?)
2 The answer would seem to be correct.
(Does it mean the speaker is hesitating?)
3 That's what I would call annoying.
(Why is would used here? Is it hypothetical situation or what?)
I found it quite difficult to know the meaning of 'would' in these sentences. I hope someone will help me with it.
