The anonymous author of A Dictionary of Blunders has a thing about syllabic /l/:
BRIDAL should not be pronounced bri’-dle, but as spelled, bri’-dal.
GRAVEL … should not be pronounced grav’-l, but grav’-vel.
MEDAL … should be pronounced med’-al, not med-dle.
MORTAL … should not be pronounced mor’-tle, but mor’t?l.
But he makes no comment on the pronunciation of gambol, while saying it must not be confused with gamble, and we also find
GARDEN should not be pronounced gar’-den, nor ge-a’r-den, but gar’-d’n.
SUDDEN. This word is occasionally pronounced sud’dn, instead of sud’-den, as spelled.
If garden and sudden are allowed with syllabic /n/, then why not allow syllabic /l/ in the other words? I can see some sort of point to bridal/bridle and medal/meddle, as he may feel that the words need to be distinguished in pronunciation as in spelling, but there is no word ‘gravvle’ or ‘mortle’.
