Alternation ‘Wh-complement’ (Uncoded)

Verbs of cognition, and some verbs of perception, can take embedded wh-complements, e.g. I know what to do, I couldn't think how to do it, She knew/asked/wondered where it was. The construction is sometimes termed an "embedded question" but this is misleading terminology. A better term would be "knowledge complement".
