Grain that grows in instalments I hear (6)
I believe the answer is:
cereal
'grain that grows' is the definition.
'cereal' can be an answer for 'grain' (synonyms). I am not certain of the remainder of the definition.
'in instalments i hear' is the wordplay.
'in instalments' becomes 'serial' (I've seen this before).
'i hear' indicates a 'sounds like' (homophone) clue.
'serial' sounds like 'CEREAL'.
Can you help me to learn more?
(Other definitions for cereal that I've seen before include "Something for brekkie" , "Eg, wheat, rye, corn" , "Starchy grains used as food" , "Relating to grain" , "Grass cultivated for food" .)
