I've been wondering where the nucleus is located in a sequence of numbers like “0404”, where the last two digits are repeated items. Given the fact that the nucleus is not placed on the last two in “7252”, is the proper place for the nucleus on the first "four"?
It is true that in strings of four numbers (or letters) where the last item is identical to the second we accent them as if contrastive focus were involved, with accents placed on the first and third.
- 7252 ˈseven (ˈ)two ˈfive two
- 8303 ˈeight (ˈ)three ˈoh three
- 2686 ˈ two (ˈ)six ˈeight six
But if the first and third items are also identical, this doesn’t apply: we revert to the usual final nucleus placement.
- 7272 seven (ˈ)two (ˈ)seven two
- 1515 ˈone (ˈ)five (ˈ)one ˈfive
- 0404 ˈoh (ˈ)four (ˈ)oh ˈfour
And similarly with initials.
- AC/DC ˈay (ˈ)see ˈdee see
- FAFA ˈ eff (ˈ)ay (ˈ)eff ˈay
