Thomas loses article to funny insect (5)
I believe the answer is:
moths
'thomas loses article to funny insect' is the definition.
I can't tell whether this defines the answer.
'thomas loses article to funny' is the wordplay.
'loses' suggests deleting specific letters.
'article' becomes 'a' (the indefinite article in English).
'to funny' indicates an anagram.
'thomas' with 'a' removed is 'thoms'.
'thoms' is an anagram of 'MOTHS'.
Can you help me to learn more?
(Other definitions for moths that I've seen before include "Insects related to butterflies" , "Nocturnal insects that breed in cloth" , "They're attracted to light" , "Night-flying insects" .)
