His French friends are in hotels (6)
I believe the answer is:
hamish
'his' is the definition.
The definition and answer are not the same part of speech.
'french friends are in hotels' is the wordplay.
'french friends' becomes 'amis' (I've seen this in another clue).
'are in' is an insertion indicator.
'hotels' becomes 'HH' (two H's - Hotel is H in the phonetic alphabet).
'amis' going inside 'hh' is 'HAMISH'.
Can you help me to learn more?
(Another definition for hamish that I've seen is " Scottish boy's name".)
