Weird. To me, it is:

tool, pool, spool, rule, school, fool (not like wool)
pull, bull, null, wolf
gulf (definitely not the same as wool) the ulf is evident

wool is not quite like tool or pull or gulf

"Can't pull the wool over my eyes" wool and pull are not the same It's not "Can't pull the wull over my eyes" In that example, it is probably closer to tool and pool but not quite.




>>Well, when I think about it, to me 'bull', 'pull' and 'full' are pronounced as in 'wool', but 'cull', 'dull', 'gull', 'hull', 'lull', 'mull', 'null' are pronounced as in 'gullet'. Do you pronounce them all the same?

>Yeah, I'd followed that chain mentally, as well. Definitely agree on "bull," "full," and "pull." I do hear a slight difference for some of the others, but don't even know how to spell the two sounds differently. My instinct for both of them is "uh." "Cull" is definitely in the second group. Most of the others fell right to me either way.
