The vast majority of compound words are constructed from a headword and a prefix (ex-sailor, semi-detached, anti-hero ); a headword and a suffix (shoot-out, phone-in, crack-down ) or with two or more different parts of speech (two nouns = book-end;noun and verb = joy-ride;two verbs = dry-clean, etc).
Is 'The vast majority of compound words are constructed from with two or more different parts of speech' right?
Is it the same as 'From underneath the trees we watch the sky.'?
In the two sentences, 'from' precedes a preposition.
