3.154 commenting on something

If you want to show your opinion of something by indicating what the experience of doing something to it is like, you can use a 'to'-infinitive clause after a complement.

The complement can be an adjective, or it can be a noun group consisting of 'a' or 'an' followed by an adjective and a noun.

Note that the 'to'-infinitive must be the 'to'-infinitive of a transitive verb or of an intransitive verb followed by a preposition.
