Crazily, Trump worsened international speed of data capture (5,3,6)
I believe the answer is:
words per minute
'speed of data capture' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'crazily trump worsened international' is the wordplay.
'crazily' indicates anagramming the letters.
'international' becomes 'i' (abbreviation eg in IMF).
'trump'+'worsened'+'i'='trumpworsenedi'
'trumpworsenedi' anagrammed gives 'WORDS PER MINUTE'.
Can you help me to learn more?
(Another definition for words per minute that I've seen is " used to evaluate speed of performer in pool?".)
