Sent for paramedics, initially, getting old (5)
I believe the answer is:
paged
'sent' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'paramedics initially getting old' is the wordplay.
'initially' suggests taking the first letters.
'getting' means one lot of letters go next to another.
'old' becomes 'aged' (similar in meaning).
The first letter of 'paramedics' is 'p'.
'p'+'aged'='PAGED'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for paged that I've seen before include "called by Speaker" , "Summoned over a PA system" , "Called a name over a PA system" , "Called over a public address system" , "Called to phone" .)
