Feel excited anticipation in time at fireside (6)
I believe the answer is:
tingle
'feel excited anticipation' is the definition.
'time at fireside' is the wordplay.
'time' becomes 't' (abbreviation).
'at' means one lot of letters go next to another.
'fireside' becomes 'ingle' (term for a fireplace).
't'+'ingle'='TINGLE'
'in' acts as a link.
(Other definitions for tingle that I've seen before include "Prickling or slightly stinging sensation" , "Feel slight stinging sensation" , "Sensational thrill" , "Shiver down the spine?" , "Slight prickling sensation" .)
