The word "sped up" is a combination of two separate words: "sped" and "up".
1. The word "sped" comes from the verb "speed", which dates back to Old English in the 9th century. In Old English, it was spelled "spēdan" and meant "to prosper, succeed, or go fast". This verb derived from the Proto-Germanic word "spōdijanan", meaning "to hasten" or "to succeed". Over time, "speed" adopted the meaning of moving quickly or fast.
2. The word "up" is a preposition and adverb that originated from Old English as well. In Old English, it was spelled "ūp" and had the same meaning as the modern usage, denoting an upward direction or movement.
