Just a little coat tail, nowadays (3)

I believe the answer is:

tad

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

'just a little' is the definition.
I can't judge whether this definition defines the answer.

'coat tail nowadays' is the wordplay.
'tail' indicates one should take the final letters.
'nowadays' becomes 'ad'.
The final letter of 'coat' is 't'.
't'+'ad'='TAD'

Can you help me to learn more?

(Other definitions for tad that I've seen before include "Smidgen" , "A small amount (colloq.)" , "Little bit" , "Slight amount" , "little boy" .)

I've seen this clue in the Evening Standard.
