I think it’s only a single word, but maybe it would be worth adding ‘sp’ for /z/ as in ‘raspberry.’ The suggested etymologies I’ve seen show both the ‘s’ and ‘p’ as part of the first root word. I suppose you could also think of it as a normal ‘s’ > /z/ and a silent ‘p’ (probably due to being next to the similar /b/).
A couple more ideas for rare ones, just in case it’s helpful:
– ‘sc’ as /z/ as in ‘crescent’ (I have /z/ here, though it seems sources often list both /s/ and /z/ for US and UK)
– ‘sth’ as /z/ as in ‘asthma’ (this one seems specifically US, so not sure if it’s worth listing or not)
