Infantile type, possibly crabby about the Fourth of July (7)
I believe the answer is:
crybaby
'infantile type' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'possibly crabby about the fourth of july' is the wordplay.
'possibly' is an anagram indicator.
'about' indicates putting letters inside.
'the fourth of july' becomes 'y' (4th letter of 'july').
'crabby' is an anagram of 'crbaby'.
'crbaby' going around 'y' is 'CRYBABY'.
Can you help me to learn more?
(Other definitions for crybaby that I've seen before include "One prone to tears" , "One shedding tears frequently" , "Person often shedding tears" , "(Very young?) weeper" , "Immature weeper" .)
