Mo*rose"ness, n.
Sourness of temper; sullenness.
Learn good humor, never to oppose without just reason; abate some degrees of pride and moroseness.
I. Watts.
⇒ Moroseness is not precisely peevishness or fretfulness, though often accompanied with it. It denotes more of silence and severity, or ill-humor, than the irritability or irritation which characterizes peevishness.
