The problem with alien food processors (5)
I believe the answer is:
teeth
'food processors' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'the problem with alien' is the wordplay.
'problem' indicates anagramming the letters.
'with' means one lot of letters goes inside another.
'alien' becomes 'et' (extra terrestrial).
'the' is an anagram of 'teh'.
'teh' placed around 'et' is 'TEETH'.
Can you help me to learn more?
(Other definitions for teeth that I've seen before include "Projections on a gear" , "symbols of legal power?" , "Food may get stuck in them" , "Effective power" , "Incisors, say" .)
