Express messages and intimate letters sent primarily in this way (6)
I believe the answer is:
emails
'this way' is the definition.
Although both the answer and 'way' are nouns, they are not in the same form of the noun.
'express messages and intimate letters sent primarily' is the wordplay.
'primarily' suggests taking the first letters.
The initial letters of 'express messages and intimate letters sent' is 'EMAILS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for emails that I've seen before include "Electronic communications" , "Computer communications" , "Electronic messages" .)
