When something gets smaller in size or amount, it has shrinkages.
Shrinkages can be a problem if you want something to stay the same size or amount.
Examples:
The shrinkages in the sweater made it too small to wear.
We have to find a way to stop the shrinkages in our savings.
The shrinkages in the cake made it look funny.
The shrinkages in the candy were so big, it was like they disappeared!
The shrinkages in the river were so big, it was like the river was gone!
The shrinkages in the balloon were so big, it was like the balloon was never there!
