Kahlo say delivered in fits and starts? (5)

'kahlo' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'delivered in fits and starts?' is the wordplay.
'delivered' becomes 'rid' (as in ridding or delivering someone of something).
'in' means one lot of letters goes inside another.
'starts?' suggests taking the first letters (I've seen 'starts' mean this).
The first letters of 'fits and' is 'fa'.
'rid' inserted inside 'fa' is 'FRIDA'.

'say' acts as a link.

Can you help me to learn more?
