If necessary, move slowly with a light touch intially (8)

'if necessary move slowly' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'a light touch intially' is the wordplay.
I cannot really see how this works, but
'a' is found in the answer.
'touch' could be 'pinch' (synonyms) and 'pinch' is found in the answer.
The remaining letters 'ta' 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).

'with' is the link.

Can you help me to learn more?
