Farmer's leg is broken (5)

I believe the answer is:

giles

I'm a little stuck... Click here to teach me more about this clue!

'farmer's' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'leg is broken' is the wordplay.
'broken' is an anagram indicator.
'leg'+'is'='legis'
'legis' anagrammed gives 'GILES'.

Can you help me to learn more?

(Other definitions for giles that I've seen before include "-- Coren; -- Brandreth" , "Farmer --- of Ham (Tolkien)" , "Sir - Gilbert Scott, English architect" , "Carl _____, newspaper cartoonist" , "Boy's name" .)

I've seen this clue in The Sun.
