No, actually.  I understand that, strictly speaking, a minimal pair can't be
used with a phoneme on a morpheme boundary (and "teethe" is just "teeth" with a
[+voice] morpheme that makes verbs--the same you find in "house" n. vs. "to
house" v.)

And that's kinda what makes it difficult, as most normal [D] *are* sitting on
morpheme boundaries, if not actually morphemes themselves (like [D] deictic and
[D] 2nd person archaic familiar).

I still like "arrhythmology" vs. "arithmology" ([D] vs. [T], "study of abnormal
heartbeat" and "study of numbers").

Someone [foreign, whose post I can't find at the moment] mentioned that the
difference between their /f/ and /v/ was mostly fortis/lenis rather than

Last night I developed a hypothesis that Australian does the same thing with /T/
and /D/, which my brain came up with as an explanation for why at least two or
three Australians on this list had trouble finding the 'voicing' in /D/.  Does
that sound plausible?

Anyway, I reeeeeally think English interdentals belong in the FAQ.
