sentimentalist:
(plural: ‘sentimentalists‘; for the right pronunciation of this word, please click here)
a person who has too much sentiment in his feelings, ideas, views, etc.;
a romanticist (in the sense of art and literature),
Every person may be sentimental at times, but a sentimentalist has sentimentalism in their thoughts, views, and deeds in a broader sense.
Those sophisticated people who believe that sentimentalists, especially in art and literature, have little knowledge in reasoning and logic are actually ignorant of the beauty of sentimentalism.
Even hard-hearted practical people can be sentimentalists when it comes to appreciating the beauty of nature and for the love they feel for someone or something and for the feeling they have for something to last forever.
