Suggest a tip (5)
I believe the answer is:
point
I believe this is a double definition.
'suggest' is the first definition.
(thesaurus)
'a tip' is the second definition.
('point' can be a synonym of 'tip')
(Other definitions for point that I've seen before include "Sharp end - purpose" , "how to repair masonry" , "Full stop; cricket position" , "... indicate location" , "rocks?" .)
