I have read all the dictionaries and surfed the web to find out the nuance between the words: "sentimental" and "emotional", but I'm not able to explain their semantic difference if it comes to! As a reply to a thread on stackexchange, mfe said:
Use sentimental to indicate mood, as in someone who reflects on his/her feelings.
Use emotional to indicate someone who reacts to events by expressing what he/she feels.
Sentimental connotes an internalized feeling, emotional an expressive one.
But actually I guess rarely non-native people would be able to use these two words in their correct places based on a simple definition.
So I wonder if you could provide me with some particular examples so that I could distinguish between these two.
Also I read about the adjective "sentimental" that mostly it is used to refer to the past memories.
A sentimental person is strongly influenced by emotional feelings, especially about happy memories of past events or relationships with other people, rather than by careful thought and judgment based on facts.
I would be greateful if you explain that to me.
