Husband standing below flag of European nation (5)
I believe the answer is:
irish
'european nation' is the definition.
'Irish' can be an answer for 'nation' (Irish is an example). I'm not sure about the 'european' bit.
'husband standing below flag' is the wordplay.
'standing' indicates taking the first letters.
'below' means one lot of letters go next to another (in a down clue, some letters go below others).
'flag' becomes 'iris' (type of iris flower).
The initial letter of 'husband' is 'h'.
'h' after 'iris' is 'IRISH'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for irish that I've seen before include "From Dublin maybe" , "From Cork, for instance" , "Celtic language" , "Reddish-brown dog" , "From Dublin, perhaps" .)
