I believe the answer is:

apoplectic

I'm a little stuck... Click here to teach me more about this clue!

'furious' is the definition.
Although both the answer and definition are adjectives, I can't see how one could define the other.

'tech company admitting nothing initially causes tension in court' is the wordplay.
'tech company' becomes 'apple'.
'admitting' is an insertion indicator.
'nothing' becomes 'O' (O resembles 0).
'initially' says to take the initial letters.
The first letters of 'causes tension in court' is 'ctic'.
'apple' placed around 'o' is 'apople'.
'apople'+'ctic'='APOPLECTIC'

Can you help me to learn more?
