tremendously, very, great, exceedingly
甚 centers on an extreme degree: something tremendously great, very much, or exceedingly so. It intensifies whatever it describes.
甚 is thought to combine 甘 (sweet) with 匹 (pair/match), suggesting an excess of sweetness or pleasure that becomes extreme. The exact historical development is uncertain.
The top 甘 looks like a container of something sweet, and the bottom 匹 suggests a matched pair. Imagine a pair of overflowing sweet jars: the amount is tremendously great.
For ジン, picture a ginormous jar of sweets: gin -> ジン, and the jar is exceedingly full.
