1. Mawkish: mushy and gushy; icy-sticky sentimental. Maudlin. Do gushy and mushy usually mean like a couple is very mushy.. Maudlin means the same thing?
2. Morbid: given to unwholesome thought; moody; characteristic of disease. Unwholesome here means not normal, not healthy? morbid means something abnormal, relating to disease?
3. What's the difference between 'pliable' and 'pliant'?
Mushy - soft and squashy [mushy peas are peas that are boiled and squashed]
Gushy - overflowing and overblown
Unwholesome thought - thinking so much about something that it affects the spirits and produces depression.
Morbid medically is "of the nature of OR indicative of disease".
Non-medically it means to have an unhealthy interest in unpleasant things, particularly death.
Pliant/Pliable are synonymous. There is no semantic difference.
