In a state of shock? That’s funny, in a good way (6)

I believe the answer is:

aghast

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

'in a state of shock?' is the definition.
I can't tell whether this definition defines the answer.

'that's funny in a good way' is the wordplay.
'that's funny' becomes 'ha' (ha is a laugh).
'in' indicates putting letters inside.
'good' becomes 'g' (abbreviation).
'way' becomes 'st' (abbreviation for street).
'a'+'g'+'st'='agst'
'ha' inserted inside 'agst' is 'AGHAST'.

Can you help me to learn more?

(Other definitions for aghast that I've seen before include "Appalled, filled with consternation" , "Deeply shocked" , "Stupefied with horrer" , "Filled with horror or shock" , "Horrified, filled iwth consternation" .)
