Tip on triangular sword's conical housing (5)
I believe the answer is:
tepee
'conical housing' is the definition.
'tepee' can be an answer for 'housing' (tepee is a kind of housing). I'm not certain of the 'conical' bit.
'tip on triangular sword's' is the wordplay.
'tip on' becomes 't' (I can't explain this - if you can you should give a lot more credence to this answer).
'triangular sword' becomes 'epee' (I've seen this in another clue).
't'+'epee'='TEPEE'
Can you help me to learn more?
(Other definitions for tepee that I've seen before include "Wigwam" , "Native American dwelling" , "Wherein Sioux" , "temporary shelter" , "Conical tent" .)
