Consonant clusters

Posting about Sprite recently, specifically mentioning consonant clusters, reminded me that I have not fully explored these in this blog. Some time ago I posted a list of common words with the possible clusters of English, but didn’t analyse the clusters themselves.

All of the two-phoneme initial consonant clusters in English start with /s/ and/or finish with /w/, /l/, /r/ or /j/ (the ‘y’ sound in you, not the ‘j’ sound in jewel). Starting with: 
/sw/ switch, suede
/sl/ sleep, slow

The other ones starting with /s/ are:
/sm/ small, smile
/sn/ snow, snap
/sp/ speak, spend
/st/ state, still
/sk/ school, scale, skin
the rare, Greek /sf/ (sphere, sphinx)
and the very rare, Greek /sθ/ (sthenic (I don’t know what this means, but it appears on lists of consonant clusters)

The ones ending in /w/ are:
/tw/ twenty, twelve
/dw/ dwell, dwarf
/kw/ question, quite
/gw/ guava, Guam
/θw/ thwart

The ones ending in  /l/ are:
/pl/ place, play
/bl/ black, blood
/kl/ close, clear and scientific words starting with chl
/gl/ glass, glance
/fl/ floor, flat

The ones ending in /r/ are:
/pr/ problem, provide
/br/ bring, break/brake
/tr/ try, train
/dr/ draw, drive
/kr/ create, cross and many Christian and scientific words (chrome, chrono-)
/gr/ great, group
/fr/ from, phrase
/θr/ three, through
/ʃr/ shrug, shrink

Finally, the ones ending in /j/ are:
/mj/ music, museum
/nj/ new/knew, nuisance
/pj/ pupil, pure
/bj/ bureau
/tj/ tune, tube
/dj/ during, duty
/kj/ queue/cue, curious
/fj/ future, fuel
/vj/ view
/hj/ huge, humour

m small, smile

(I tried to make a table unambiguously showing which combinations are possible and which aren’t, but couldn’t make one that is both complete and clear.)
