Crossword Genius

A little 'thank you' letter (3)

Ross

I believe the answer is:

tad

'a little' is the definition.
(I've seen this before)

'thank you letter' is the wordplay.
'thank you' becomes 'ta'.
'letter' becomes 'd' ().
'ta'+'d'='TAD'

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