Help suspect, initially getting guts to dummy-spit (6)
I believe the answer is:
phlegm
'dummy-spit' is the definition.
I can't judge whether this defines the answer.
'help suspect initially getting guts' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'initially' says to take the initial letters.
'guts' becomes 'm' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The first letter of 'getting' is 'g'.
'help' is an anagram of 'phle'.
'phle'+'g'+'m'='PHLEGM'
'to' is the link.
Can you help me to learn more?
(Other definitions for phlegm that I've seen before include "Mucous lodged in throat" , "Secretion from throat" , "Mucus - self-possession" , "Mucus - stolidity" , "indifference" .)
