Ham, perhaps the ultimate in Tyrolese speck (5)
I believe the answer is:
emote
'ham' is the definition.
(I've seen this before)
'the ultimate in tyrolese speck' is the wordplay.
'the ultimate in' says to take the final letters (take the ultimate ie last letter).
'speck' becomes 'mote' (synonyms).
The final letter of 'tyrolese' is 'e'.
'e'+'mote'='EMOTE'
'perhaps' is the link.
(Other definitions for emote that I've seen before include "Behave theatrically" , "Give expression to one's feelings" , "Go over the top" , "Show excessive passion" , "Portray feelings theatrically" .)
