Alert Pompeo and Rudy for starters — time to get involved (5)
I believe the answer is:
pager
'alert' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'pompeo and rudy for starters time to get involved' is the wordplay.
'pompeo' becomes 'p' (this could be a standard abbreviation of which I'm unaware).
'and' says to put letters next to each other.
'for starters' suggests taking the first letters.
'time' becomes 'age' (age is a kind of time).
'to get involved' indicates putting letters inside.
The first letter of 'rudy' is 'r'.
'p'+'r'='pr'
'pr' placed around 'age' is 'PAGER'.
Can you help me to learn more?
(Other definitions for pager that I've seen before include "This may summon one" , "One calling" , "Electronic alerting device" , "Radio alert device" , "Electronic messaging device" .)
