The quantifier "some" is one of a number of words in English which has not only a full form (some), but a reduced form too (sm). It is not uncommon to read that this or that meaning is attached to one and only one of these forms, usually to "stressed" some. In the prosodic literature on the other hand, differences between the two forms is sometimes explained in terms not of meaning, but of prosodic phrasing.
This paper presents work in progress on the meanings and prosodic forms of English "some". What I have found is that there are at least three dimensions to the prosodic realisation of some: reduced/unreduced, rhythmically strong/weak, accented/unaccented. None of these correlate completely with another, and nor do any of them correlate completely with any particular meanings. As has happened often in the field of prosody, the picture is more complicated than what is usually taken for granted.
