In random chat, lie is moral (7)

Ross

I believe the answer is:

ethical

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

'moral' is the definition.
(synonyms)

'in random chat lie' is the wordplay.
'chat lie' anagrams to 'ETHICAL'.
But, I am not clear how the anagram is indicated.

'is' acts as a link.

Can you help me to learn more?

(Other definitions for ethical that I've seen before include "Morally correct, in accordance with professional standards" , "Abiding by moral principles" , "Morally correct, honourable" , "Moral, principled" , "Morally good or correct" .)
