A random Latin question for those who know:
Do vowels in ecclesiastical Latin have more than one sound (short / long)?
no, [....]
Too perfect! I can't think of a better choice for someone to emerge from the
Novus Ordo smoke-of-Satan, and then provide readers with the
wrong answer.
Which is not to claim that it makes him unique among the
Novus Ordo faithful: According to reports, even that guy garbed in white in
Vatican City nowadays has shown that he does
not have a useful level of skill with
Latin.
[...] but double vowels have a pronunciation that is longer in duration for example in "tuum" the length of the pronunciation of the u is similar to the a'a in ma'am.
It is not a longer u, but two "u's " both pronounced, as tu-um.
That is the same as the double a in ma'am
Ecclesiastical Latin does indeed have vowels whose sounds are distinguished as
short versus long. And ironically, that's exemplified by the 4-letter word that's already been offered, albeit for the
wrong reason. The sounds of the 2 '
u' in
ecclesiastical Latin "
tū-um" are significantly different (from each other), the word being pronounced approximately as "
too'-(w)uhm", thus the 1st vowel being ' ū ' (i.e.: long), and the 2nd vowel being ' ŭ ' (i.e.: short).
-   That's in contrast to "tuh'-uhm in classical Latin, in which both vowels are short.
So a correct answer about Latin should be credited to 'Nadir'.
As for the pronunciation of the English contraction "ma d am", it almost certainly exhibits U.S.-regional differences. E.g., in the Deep South, it's more like "mah'-yahm" or "mah'-yuhm", where the vowel sounds shown as "ah" in this instance are approximately the sound of the Old-English letter 'æ', which is exemplified by the (letter's) name in modern English: "ash".
Note *: I trust that the computers at CathInfo Hq., and those of other established members of CathInfo, have already been equipped with fonts that're able to display what've been called the Pan-European characters of the Universal Character Set a.k.a. Unicode. Textbooks for Latin were one of the reasons compelling the inclusion of Latin-alphabet vowelsprecomposed with the breve (short-sign) and the macron (long-sign).
