American in charge of old journal blocks my study (10)
I believe the answer is:
musicology
'study' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'american in charge of old journal blocks my' is the wordplay.
'american' becomes 'us' (abbreviation for United States).
'in charge of' becomes 'ic'.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'journal' becomes 'log' (I've seen this in other clues).
'blocks' is an insertion indicator (the inside letters form a 'blockage').
'us'+'ic'+'o'+'log'='usicolog'
'usicolog' going within 'my' is 'MUSICOLOGY'.
Can you help me to learn more?
(Another definition for musicology that I've seen is " sound discipline".)
