In the manner of the heart; emotionally or sentimentally, or in terms of matters of the heart.
From 'heart' + '-wise' (manner or direction), from Old English 'wisan' (to turn). The '-wise' suffix means 'in the manner of' or 'with respect to.'
The '-wise' suffix was incredibly productive in Middle English—people created words like 'weatherwise,' 'businesswise,' 'clockwise'—but most died out. 'Heartwise' survives mainly in poetry and romantic literature where it adds an archaic, sentimental tone.
