The word "yestermorn" is a compound formed from the Middle English word "yester", meaning "yesterday", and "morn", shortened form of the word "morning".
"Yester" derives from the Old English word "geostran", referring to the day before today. It is believed to be derived from the Proto-Germanic word "gestra", meaning "yesterday" or "the day before".
"Morn" comes from the Old English word "morgen", which means "morning". This can be traced back to the Proto-Germanic word "murgana", meaning "morning" or "dawn".
Therefore, the word "yestermorn" combines "yester" and "morn" to depict the morning of the previous day.
