Words I kind of love. For not particular reason, I just do.

chained_bear I think the boys tend* to do that in their sketches, don't they?
*using present tense because I refuse to believe Fry & Laurie will ever cease. :) Aug 18, 2009
yarb I don't think it's that common a pronunciation - at least the Fry & Laurie clip is the first time I've encountered it. I suppose it makes sense re: mandate, but I suspect Fry may be speaking in character here, i.e. for comedic effect. Aug 18, 2009
Telofy Thanks! So it's probably something obscure or new-fangled and British. Aug 18, 2009
qroqqa I can't play sound clips, but if it's just [mænˈdeɪtəri], I would assume that's a common pronunciation, and surely there's nothing strange about it. Myself, I say [ˈmændətri] with initial stress, which is probably the older pronunciation—mine usually are, when I look them up. Aug 18, 2009
seanahan Wow, that pronunciation is really jarring, I've never heard it said like that before. I'm not sure if it is a British thing or a comic thing. Aug 18, 2009
Telofy Can someone tell me why Stephen Fry stresses mandatory on the second syllable in this video (around 1:28)?
I'm especially interested in that because some time ago I used to read it (hopefully never aloud) that way for a while before I noticed the mistake. Aug 16, 2009
