To meaning

Context would be helpful. Are you talking about the movie, The Silence of the Lambs?

"What do these sentences mean?"

They are not sentences.

Why?

No these are sentences of the dictionary about "to"

Ah, now I see.

And they are definitely not sentences. Sentences are complete thoughts. These are not. They are just examples of using the word 'to' in various ways.

They are not "sentences". They are phrases illustrating how the word 'to' can be used.

Thank you very much all.

Tara: "Yes they don't know explain them for me.
