Our US board members use ‘spelled’ and found ‘spelt’ (an acceptable UK version) decidedly odd.
It’s certainly not normal US usage, but a well-read American will recognize it as the common UK spelling. The only person who I recall making an issue of this was wordgeek, who may have been Zeta Reticulan rather than American.
Having had a chance to check on builded in the King James Bible, I find that it and built were both used, apparently indiscriminately.
Genesis 8:20
And Noah BUILDED an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.
Genesis 22:9
And they came to the place which God had told him of; and Abraham BUILT an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood.
I suppose this sort of inconsistency is inevitable in documents written by committees.
BTW, I would add bent to OPT’s list of universals; at least I don’t recall bended as standard anywhere.
