Syn. -- Friendly; peaceable; kind; harmonious. -- Amicable, Friendly. Neither of these words denotes any great warmth of affection, since friendly has by no means the same strength as its noun friendship. It does, however, imply something of real cordiality; while amicable supposes very little more than that the parties referred to are not disposed to quarrel. Hence, we speak of amicable relations between two countries, an amicable adjustment of difficulties. “Those who entertain friendly feelings toward each other can live amicably together.” [ 1913 Webster ]

n. The quality of being amicable; amicability. [ 1913 Webster ]

adv. In an amicable manner. [ 1913 Webster ]
