1. Having, expressing, or containing a sentiment or sentiments; abounding with moral reflections; containing a moral reflection; didactic. Nay, ev'n each moral sentimental stroke, Where not the character, but poet, spoke, He lopped, as foreign to his chaste design, Nor spared a useless, though a golden line. (whitehead)
2. Inclined to sentiment; having an excess of sentiment or sensibility; indulging the sensibilities for their own sake; artificially or affectedly tender; often in a reproachful sense. A sentimental mind is rather prone to overwrought feeling and exaggerated tenderness. (Whately)
Sentimental, romantic. Sentimental usually describes an error or excess of the sensibilities; romantic, a vice of the imagination. The votary of the former gives indulgence to his sensibilities for the mere luxury of their excitement; the votary of the latter allows his imagination to rove for the pleasure of creating scenes of ideal enjoiment. Perhaps there is no less danger in works called sentimental. They attack the heart more successfully, because more cautiously. . I can not but look on an indifferency of mind, as to the good or evil things of this life, as a mere romantic fancy of such who would be thought to be much wiser than they ever were, or could be. .
