Voracious eater’s place at head of table (6)
I believe the answer is:
locust
'voracious eater's place at head of table' is the definition.
I can't judge whether this defines the answer.
'place at head of table' is the wordplay.
'place' becomes 'locus' ('place' in Latin).
'at head of' means one lot of letters go next to another (some letters go in front of others).
'table' becomes 't' (this could be a standard abbreviation of which I'm unaware).
'locus'+'t'='LOCUST'
Can you help me to learn more?
(Other definitions for locust that I've seen before include "It strips plants" , "Vegetation-destroying grasshopper" , "plaguey type" , "Destructive migratory insect" , "Predatory grasshopper that swarms" .)
