a constant lover.
a man constant in adherence to his ideals.
constant as the northern star.
in constant pain.
maintained a constant temperature.
man's unceasing warfare with drought and isolation.
night and day we live with the incessant noise of the city.
principles of unvarying validity.
the ceaseless thunder of surf.
the never-ending search for happiness.
the perpetual struggle to maintain standards in a democracy.
the velocity of light is a constant.
unremitting demands of hunger.
