Tentative suggestions put out by some animals? (7)
I believe the answer is:
feelers
'tentative suggestions' is the definition.
'feelers' can be an answer for 'suggestions' (feeler is a kind of suggestion). I'm not sure about the 'tentative' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for feelers that I've seen before include "Tentative exploration" , "horns" , "Antennae or cautious proposals" , "Probes" .)
