Taint one word tho is it?
It's two words hyphenated! AND I've just realised that 'P' 'Q' and 'R' have been missed out! Then from 'T' we've somehow gone back to 'I' This is A-Z!
Starting with 'P' then:
Phyllosan (Fortifies the over-forties)
Quadrophenia (Film)
Ralgex
Now then: We're up to 'T' so the next one is 'U' - Your shot!
