Get, Got, Gotten.
Okay, for most purposes these words grate on my sensibilities.
I understand 'Get' as meaning 'fetch' or 'go and fetch', not as statements of possession.
So "I've got that" means "I have been and fetched that". I may have used it as a child, as with card collections "Oh, I've already got that one" But "I've" is a contraction of "I have" so "I've got" (unless referring to fetching) means "I have have". This is somewhat tautologous.
I am, however, happy to accept a hymn starting "Of the Father's love begotten" on the basis that I've been brought up with it, and it is of a different era.

Having typed this, I'm a little surprised to find that although some uses annoy me, I'm happy with others.

Oh well, maybe I'm human!
