IPA: /ˈsɪŋkɪdʒ/
KK: /sɪŋkɪdʒ/
The act or process of something sinking down, creating a lower area or depression.
The heavy rain caused significant sinkage in the road, making it difficult to drive.
Sinkage → It is formed from "sink" (from Old English "sincan", meaning to go down or descend) and "-age" (a suffix used to form nouns indicating a state or condition). The word "sinkage" refers to the state or condition of sinking or going down.
Think of something that is 'going down' ('sink') and the '-age' indicating a state or condition — that's why sinkage means the state of sinking.
