Hi Ethan!
Sentiment has more to do with “organized” feelings, if you know what I mean.
e.g. “There’s no display of sentiment in their relationship.”
“There is no room for sentiment in situations that require harsh decisions.”
Feeling is related to something specific that you feel through your mind and/or senses.
e.g
“During this pandemic, many men and women are dealing with feelings of isolation and loneliness.”
Is it clear?
I hope this helps.
Keep up the good work!
