Iraqi and Syrian leaders call out for insurrection (6)
I believe the answer is:
rising
'for insurrection' is the definition.
(synonyms)
'iraqi and syrian leaders call out' is the wordplay.
'iraqi' becomes 'i' (this might be a standard abbreviation of which I'm unaware).
'and' means one lot of letters go next to another.
'leaders' suggests taking the first letters.
'call' becomes 'ring' (telephone call).
'out' indicates putting letters inside.
The first letter of 'syrian' is 's'.
'i'+'s'='is'
'is' going within 'ring' is 'RISING'.
Can you help me to learn more?
(Other definitions for rising that I've seen before include "Upward rebellion?" , "A revolt; getting up" , "Ascension" , "Revolt; increasing" , "Moving upwards" .)
