may have heard versus probably have heard

[duiter]

Hi all,

What is the difference between 'may have heard versus probably have heard' ?

for example :

He 'may have heard' the rumour

He 'probably have heard' the rumour

Is there any meaning difference ?

Thanks

Hi all,

He 'may have heard' the rumour. With auxillary verbs like "may", the base form "have" is kept.

He 'probably has heard' the rumour. With an adverb like "probably", say 'He probably has...'.

Is there any difference in meaning? (is much better)
'may" means it's possible. "probably" means a more than 50% likelihood.
Thanks
