1) Would you please tell me the difference in meaning between the following verbs? I would also appreciate if you could give me sentences as illustrations.

a) “forbear / forsake / forswear” ?

b) “heave” (regular) and “heave” (irregular)?

c) “crow” (regular) and “crow” (irregular)?

d) “abide” (regular) and “abide” (irregular)?

e) “cleave” (regular) and “cleave” (irregular)

2) The irregular form of the verb “to hide” is :
a) hid / hid / hidden
b) hid / hid / hid
c) both? Any difference between the 2 forms?

Many thanks,
