Being dreadfully boss like, creating landmarks (8)
I believe the answer is:
obelisks
'landmarks' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'being dreadfully boss like' is the wordplay.
'being dreadfully' indicates an anagram (a dreadful spelling).
'boss'+'like'='bosslike'
'bosslike' anagrammed gives 'OBELISKS'.
'creating' is the link.
Can you help me to learn more?
(Other definitions for obelisks that I've seen before include "Stone pillars tapering towards pyramidal tops" , "Monuments" .)
