I'm a little stuck... Click here to teach me more about this clue!

'a name' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'in hypnotism' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OTIS' is hidden within 'hypnotism'.

Can you help me to learn more?
