Literary or poetic term for the first light of morning; less common in everyday speech than 夜明け.
The sky at dawn is beautiful.
Variant spelling without the okurigana き; less common but still used.
Compound of 引き (hiki, continuative form of 引く 'to pull') + 明け (ake, continuative form of 明ける 'to dawn'), literally 'pulling dawn'. The exact derivation is uncertain; it may refer to the gradual drawing of light across the sky.
