Lend about a grand to the mountain man (5)
I believe the answer is:
logan
'mountain man' is the definition.
'Logan' can be an answer for 'man'. I am unsure of the 'mountain' bit.
'lend about a grand' is the wordplay.
'lend' becomes 'loan' (synonyms).
'about' indicates putting letters inside.
'a grand' becomes 'g' (G is short for grand as in a thousand).
'loan' placed around 'g' is 'LOGAN'.
'to the' acts as a link.
Can you help me to learn more?
(Other definitions for logan that I've seen before include "Rocking-stone" , "Rocking stone" , "Mount ..... is the highest peak in Canada" , "(Grower of) berry" .)
