Understand the meaning of "Be rational" (3,5)

I believe the answer is:

see sense

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

'be rational' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'understand the meaning' is the wordplay.
'understand' becomes 'see' (synonyms).
'the meaning' becomes 'sense' (sense is a kind of meaning).
'see'+'sense'='SEE SENSE'

'of' acts as a link.
