In the specific context of something not originally or directly known to the speaker, but heard from someone else and later reported, how do obviously, apparently and evidently modify the meaning of such statements, especially in terms of conveying the speaker's level of confidence in the veracity of what someone said?
Please note: I do not use 'apparently' here to mean 'looks so, but is not really so' as in "he is apparently a honest man (but not really one)", but in the sense 'I wouldn't know to begin with, but so-and-so says so', as in mathematics is apparently a very challenging science (I wouldn't know, but Tom says so!)
