Which word did John Stuart Mill suggest to use in place of Sociology? What was the reason to use that word?

J.S. Mill's Alternative Word for Sociology:

• Proposed Term: 'Ethology' (एथोलॉजी / चरित्र विज्ञान) — the science of the formation of character.
• Reason: Mill objected to Auguste Comte's word 'Sociology' because it was an etymological hybrid derived from two distinct languages (Latin 'Socius' + Greek 'Logos').
