[Corpora-List] Incidence of MWEs

[Will Fitzgerald]

The thing is, the various meanings of 'pencil sharpener', 'crayon
sharpener' and 'stick sharpener' are all predictable, just not from
their immediate lexical items. I think that any 'tool for Verbing
Noun' or a 'tool for Verbing, shaped like a Noun' will apply in Noun
Verb-er expressions. Certainly, because there is a greater need for
pencil sharpeners, pencil sharpeners tend to have standard shapes &
components, but a pencil sharpener that worked via laser beams would
still be a pencil sharpener. And imagine a tool for sharpening knives
that had a graphite core; in the proper context, 'pencil sharpener'
(or maybe even 'pencil knife sharpener' is ok.

The point is that general real-world knowledge, plus rules of phrasal
combination, create predictable meanings for some expressions that are
not predicatable based on the lexical meanings.

Oh, by the way, here is a 'pencil pencil sharpener':
