a dark scowl.
a dour, self-sacrificing life.
a forbidding scowl.
a glum, hopeless shrug.
a grim man loving duty more than humanity.
a mind not gifted to discover truth but tenacious to hold it.
a morose and unsociable manner.
a saturnine, almost misanthropic young genius.
a sour temper.
a sullen crowd.
dogged persistence.
dour determination.
he sat in moody silence.
men tenacious of opinion.
the most vocal and pertinacious of all the critics.
the proverbially dour New England Puritan.
undoubtedly the grimmest part of him was his iron claw.
