"I may probably be happy" does not exist. Both 'may' and 'probably' define different areas of certainty.Modal "will" is used to express the greatest amount of certainty, followed by other modals like "would", "can", "could", "may" and "might".
E.g. I will be happy tomorrow (very certain) vs. I may be happy tomorrow (not certain)
However, we do normally use "I think I will be" and "I will probably be" in speech. "I think" and "probably" are used to suggest uncertainty and it seems contradictory to use with "will" (not sure in this context it's a modal or a future "will").
'will' is a modal whether it's expressing a future sense or a emotive sense, Lycen.
All modals of 100% certainty can be modified to show a lesser level of certainty.
100% I will go.
90-99% I almost certainly will go.
51-89% I likely/probably will go.
26-50% I may go.
1-25% I might go.
0% I won't go.
[these numbers are, of course, not cast in stone. They merely provide a rough range that each covers in relation to the others.
The same can be done with "be going to + verb"/want to/have to/ need to/would/can/could/shall/... .
E.g. I will probably be happy tomorrow; I think I will be happy tomorrow
Any difference between 1. "I will probably be happy tomorrow" and 2. "I would be happy tomorrow" or 3. "I may be happy tomorrow"?
1. 51-89% chance I will be happy. 2. A conditional future; I would be happy if blah blah blah. 3. 26-50% chance I will be happy.
Is there a difference between "I will probably be happy" and "I may probably be happy"?
Logically, why does such a combination even exist?
