Beastly types love to interfere with data (6)
I believe the answer is:
stoats
'beastly types' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.
'love to interfere with data' is the wordplay.
I cannot really understand how this works, but
'love' could be 'o' (love means zero in tennis) and 'o' is located in the answer.
'data' could be 'stats' (statistics are a kind of data) and 'stats' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stoats that I've seen before include "Weasel-like mammals" , "In winter, they're known as ermines" , "European ermines" , "Short-tailed weasels" , "Their chestnut coats turn white in winter" .)
