Most courageous.

Acts sorry for misdoings.

Bodily reaction to food caught in throat.

Surrender, give in.

Chinese name for the Yellow River.

Lone singer.

The science of matter and energy.

Held against will.

Ticket allowing travel on public road transport.

Masses of frozen snow covering both poles.

Crosspiece above a door or window.

Inhabitants of Crete during the Bronze Age.

Old English epic poem translated by Seamus Heaney.
