Touching way to give a reminder (5)
I believe the answer is:
nudge
This might be a double definition.
'touching way' is the first definition.
'nudge' can be an answer for 'touching' (thesaurus). I am not sure about the 'way' bit.
'give a reminder' is the second definition.
(I've seen this before)
'to' acts as a link.
Can you help me to learn more?
(Other definitions for nudge that I've seen before include "Give a reminder" , "Prod gently with elbow" , "Gentle encouragement" , "Poke gently with elbow" , "Push with the elbow" .)
