An amusing aside: more than once, in attempting to type
feckless or --ful, I found I had typed a 'u' in place of
the first 'e'!

Apropos of absolutely nothing (as is my wont), the correct pronunciation of the very common Maori word "whaka" is basically indistinguishable from F*cka - some Anglo NZers are reluctant to pronounce it properly for that reason.
