The phrase "jammed full" is a combination of two separate words: "jammed" and "full". Each of these words has its own etymology:
1. Jammed: The word "jammed" comes from the verb "jam", which originally meant to forcibly squeeze something into a tight space or to get stuck tightly. The exact origin of the word is uncertain, but it can be traced back to the 18th century, possibly derived from the French word "jambon", meaning "ham". The association with ham may be due to the way meat is tightly packed. Over time, the meaning of "jam" expanded to encompass various other contexts, including traffic congestion and technological blockages.
2. Full: The word "full" is derived from the Old English word "full", which meant complete or whole. It shares common roots with similar words in other Germanic languages.
