Lectured about an American city in Washington (7)

I believe the answer is:

spokane

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

'american city in washington' is the definition.
I can't judge whether this defines the answer.

'lectured about an' is the wordplay.
'lectured' becomes 'spoke' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'spoke' enclosing 'an' is 'SPOKANE'.

Can you help me to learn more?

(Another definition for spokane that I've seen is " American city".)

I've seen this clue in The Hindu.
