For example:
Alcoholic -- Alcohol means... well, alcohol. The suffix "-ic" means "of or pertaining to"
Chocoholic -- Choco: a shortened form of "chocolate". The suffix "-holic" seemingly means "addicted to", though the suffix "-ic" is all that is required to denote this according to the previous example.
Is there an etymological term for this "suffix merging" that occurs? (bonus points for finding more examples of this)
Edit for Clarity
Here's an article from grammarist describing this in more detail. "Alcoholic" was coined as a combination of "alcohol" and "-ic". Then, in the 20th century, the suffix "-holic" took on the meaning of "addicted to". E.g., "shopaholic", "workaholic", "golfaholic", etc.
Is there a word for when suffixes merge into words they are modifying in this manner?
Edit #2
Another example: helicopter comes from the greek “helix” or spiral, and “pter” or “flying” yet “-copter” is the suffix used for spinning blade flying things like “quadcopter”. Of course “quadpter” doesn’t really make sense in English, but I’m interested in a term to describe the combination of “helix” and “pter” becoming a new suffix
