cygnet
Pronunciation: /ˈsɪgnɪt/
Origin:
late Middle English: from Anglo-Norman French cignet, diminutive of Old French cigne 'swan', based on Latin cycnus, from Greek kuknos
Do not confuse cygnet with signet. A cygnet is a young swan, whereas signet is usually found in the phrase signet ring, which is a ring with letters or a design on it.
