Transmitted current intelligence, sheer sloppiness! (14)

Ross

I believe the answer is:

sentimentality

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

'sloppiness' is the definition.
(I know that sloppiness can be written as sentimentality)

'transmitted current intelligence sheer' is the wordplay.
I cannot quite understand how this works, but
'transmitted' could be 'sent' ('send' can be a synonym of 'transmit') and 'sent' is located in the answer.
'current' could be 'i' (symbol for electric current) and 'i' is found in the answer.
'intelligence' could be 'mentality' (mentality is a kind of intelligence) and 'mentality' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for sentimentality that I've seen before include "Gooey feeling" , "Slush" .)
