Thought mad, making a point? (5)
I believe the answer is:
mused
'thought' is the definition.
(musing is a kind of thinking)
'mad making a point?' is the wordplay.
I cannot quite see how this works, but
'point?' could be 'se' (SE is an example) and 'se' is located in the answer.
The remaining letters 'mud' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mused that I've seen before include "Fuddled" , "Reflected or pondered" , "Was deep in thought" , "'Meditated, mulled (5)'" , "Reflected in silence" .)
