Thanks, GG. Now this is absolutely confusing to me. I always had problem with reading the pronunciation keys for American English. British pronunciations have long been standardized on IPA. Why can't American English dictionaries use IPA??? The symbols in Merriam-Webster is different from that of American Heritage. And who knows how many different sets of symbols are used by different American English dictionaries? The worst thing is that my Cambridge Pronouncing Dictionary uses a mix
of IPA with a bit of these non-standard American symbols for showing
American pronunciations!
I think the pronunciation keys in Merriam-Webster are just plain WRONG! It says
\
\ as a in abut
\ 

\ as u in abut
\
\ as e in
kitten
\
r \ as ur/er in further
\ e \ as e in
bet
\ 

\ as ea in easy
\
\ as y in easy
(Barbara, where in the pronunciation symbols page says "er" is the same sound as "air"? There is no entry for \ er \ on that page!!!)
I mean this page --> http://www.merriam-webster.com/pronsymbols.html
Am I mis-reading the symbols? Or Americans really say the vowel in bet exactly the same as that in hair??? They are obviously different in the voice recordings in Merriam-Webster.
In British English, they are two different vowels.
? ? ? ? ? It is driving me nuts!
